Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
It becomes an interesting part for the researchers to analyze the dynamical behavior of soliton propagation in optical fibers for trans-oceanic and trans-continental distances. In this paper, we desire to retrieve distinct and innovative accurate wave solutions to the dual core optical fiber nonlinear equations by adopting the improved tanh method and the rational [math]-expansion method. Consequently, a bundle of accurate wave solutions is achieved in diverse sense. The acquired solutions are made visible in the profiles of three-dimensional (3D), two-dimensional (2D) and contour shapes. The effects of the wave speed in soliton transmission are highlighted by plotting different 2D outlines in a single diagram for some obtained solutions. The employed techniques perform as before to unravel the suggested governing models for appropriate wave solutions and hence deserve to contribute in further research.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
In this work, a flat-top and broadband supercontinuum (SC) generation in photonic crystal fibers (PCFs) infiltrated with carbon tetrachloride (CCl[math] with different air hole diameters in the cladding has been introduced. The optical properties of the fundamental mode are analyzed by numerical simulation. Based on the obtained results, two optimized PCFs with small dispersion are proposed and verified against SC generation in detail. The first fiber has an all-normal dispersion of [math]9.376[math]ps.nm[math].km[math] at the pump wavelength of 0.98[math][math]m, generating broadband of 768[math]nm and flat-top with only 0.3[math]nJ of input energy and time duration of 90[math]fs. In the meantime the dispersion property of the second fiber is anomalous, which equals 1.105[math]ps[math][math][math]nm[math][math][math][math]km[math] at 1.3[math][math]m pump wavelength. The second fiber generates a SC spectrum of 1,751.1[math]nm with input energy and time duration of 0.55[math]nJ and 55[math]fs, respectively. Proposed fibers are suitable for all-fiber SC sources which could lead to new low-cost all-fiber optical systems.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
The new organic 2-amino-5-chloropyridinium phenoxyacetate (2A5CPA) nonlinear optical (NLO) crystal was synthesized and grown from methanol solvent by slow evaporation method successfully. The complete 2A5CPA crystal structure was solved by single crystal XRD analysis and it indicates that the 2A5CPA crystal belongs to the tetragonal crystal system with the space group P41212. From the structure, the possible hydrogen bonding interactions have been analyzed. The presence of distinctive functional peaks in the 2A5CPA crystal was affirmed by FTIR analysis. The optical investigation reveals that the crystal was completely transparent in the UV–Vis–NIR region. The TG-DTA investigation assured that the 2A5CPA compound is thermally stable up to 134∘C without any decomposition. The sharp endo thermic peak at 205∘C in the DTA trace indicates the melting point of the crystal. The broad emissive band at 382[math]nm implies the violet emission characteristics of the 2A5CPA crystal. The dielectric study of the 2A5CPA crystal portrays the normal behavior to that of optical materials. The high work-hardening coefficient of 2.94 indicates the soft material nature of the crystal. The LDT value of the 2A5CPA crystal is estimated as 0.6135[math]GW/cm2. The third-order NLO properties of the 2A5CPA crystal were analyzed through [math]-Scan experiment.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
The model given by Patil et al., for the self-focusing of lowest-order Bessel–Gaussian laser beam, is revisited by introducing the exponential plasma density ramp in this paper. Plasma density changes due to combined effect of the relativistic and ponderomotive nonlinearities, which arise due to the nonuniform spatial profile of the laser beam leading to stronger self-focusing. Under paraxial ray approximation, the expression for the evolution of laser-beam width parameter is obtained and solved numerically in order to achieve self-focusing. We have observed that as Bessel beam propagates through the plasma, it does not diffract and spread out, which is in contrast to the usual behavior of light that spreads out after being focused down to the small spot. Laser spot size decreases considerably under the presence of exponential density ramp. This study will be useful for better understanding the self-focusing mechanism of lasers as it becomes effective for the optimized parameters under the proposed situation. Bessel laser beams play an important role in enhancing the energy gain in laser-driven accelerators. In addition, for all laser-driven plasma-based accelerators, it appears possible to guide a laser beam over large distances using a plasma density channel, thus enhancing the acceleration length and the energy gain.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
The model of ([math])-dimensional breaking soliton equation is proposed, and the novel soliton solutions are derived by using the variable separation and extended mapping approach of Riccati equation and then, the propagation dynamics of the solutions which include multi-dromions, ring breather, fusion solitons and other multi-solitons are also constructed. Furthermore, the rich local excitations and fractal structures are investigated. The simulation results verify the proposed scheme. It can get more abundant local excitation structures than the ([math])-dimensional nonlinear systems and it has potential values for certain applications in optical field.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
In this paper, solitons solutions of higher-order dispersive cubic–quintic Schrödinger equationincluding third-order as well as fourth-order derivatives with respect to time, that describes the dynamics of ultrashort pulses in optical fibers are investigated in detail. In this respect,a solution procedure in the locality of applied mathematics called the hyperbolic function method is appliedusing multi-linear variable separation approach (MLVSA). As an outcome, a bunch of soliton solutions isderived in conjunction with plotting dark and periodic wave solutions. The credibility of the results is examined by setting each solution back into its governing equation. Through portraits, different forms of wave solutions are depicted. Moreover, the restrictions on the parameters are also given for the existence of the obtained solutions.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
The properties of nonlinear optical (NLO) are examined, and the results confirm the 2.19[math]eV HOMO–LUMO mismatch. In the AlPc cluster, certain functional bond lengths and bond angles have been observed. Quantum chemical methods (density functional theory (DFT) and time-dependent density functional theory (TD-DFT)) and vibrational spectra properties of AlPc are studied. An X-ray pattern reveals the crystalline structure along the (242) orientation of AlPc organic thin layer. An ultraviolet-visible (UV–Vis) also shows the frequency selective behavior of the device. The absorbance of such layer exhibits a high value within UV range and two consecutive peaks within the visible range. Spin coating is used to make an organic diode based on the Aluminium phthalocyanine (AlPc-Cl) molecule. Under dark and light conditions, electrical characterization of Ag/AlPc/Si/Au is obtained. The diode’s high rectifying capability (about [math] is subsequently discovered. While the height barrier is constant and saturation current is greatly reliant on light, the ideality factor of such a diode increases to 6.9 which confirms the nonideality of such a device. The Cheung–Cheung technique is employed to further the investigation and gain additional data such as series resistance and barrier height.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
TOAD or Tera Hertz Optical Asymmetric Demultiplexer is an optical switch. Using this switch, we have invented an optical comparator. This optical comparator circuit is very simple in structure with a higher speed (200 Gbps) and finds useful application in optical computation and communication network system. We have simulated all three outputs in detail and shown the eye diagram of all three outputs of the optical comparator. We found high values of extinction ratio (ER), contrast ratio (CR), and quality factor ([math] value) for the three outputs of the comparator.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
The copper oxide nanoparticles (CuO NPs) were synthesized via solution combustion approach with Bengal gram powder as a fuel. The XRD analysis confirms the monoclinic structure of CuO NPs. FT-IR spectrum reveals the formation of CuO NPs. SEM studies show that the NPs are nearly spherical, and the elemental composition was confirmed by EDAX. The absorption spectra revealed a direct optical band gap of 1.50[math]eV. DFT calculations were performed to determine the HOMO–LUMO energy bandgap and found to be 1.72[math]eV, which is in good agreement with the experimental value. The Z-scan technique was used to investigate the third-order nonlinear optical (NLO) characteristics using DPSS continuous wave laser (532[math]nm, 200[math]mW). A high reverse saturation absorption and negative nonlinear refractions were observed. Third-order NLO parameters [math], [math] and [math] were found to be [math][math]cm/W, [math][math]cm2/W and [math][math]esu, respectively. The CuO NPs also displayed strong optical limiting behavior with a limiting threshold of 2.11[math]kW/cm2.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
The Kaup–Newell equation is used to model sub-picoseconds pulses that travel throughout optical fibers. The fractional-order perturbed Kaup–Newell model, which represents extensive waves parallel to the field of magnetic, is examined. In this paper, two analytical techniques named, improved F-expansion and generalized exp[math]-expansion techniques, are employed and new analytical solutions in generalized forms like bright solitons, dark solitons, multi-peak solitons, peakon solitons, periodic solitons and further wave results are assembled. These soliton solutions and other waves findings have important applications in applied sciences. The configurations of some solutions are shown in the form of graphs through assigning precise values to parameters, and their dynamics are described. The illustrated novel structures of some solutions also assist engineers and scientists in better grasping the physical phenomena of this fractional model. A comparison analysis has been given to explain the originality of the current findings compared to the previously achieved results. The results of computer simulations show that the procedures described are effective, simple, and efficient.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
Ultrafast laser-induced periodic surface structures (LIPSSs) have been studied intensely in the last two decades, which have become a useful method for surface nanostructures and are widely used to tune surface properties. This paper reported the fabrication of high-spatial-frequency LIPSSs (HSFLs) on FTO film induced by 1,030[math]nm femtosecond laser. The morphology, duty cycle and birefringence effects of HSFLs were studied in detail by changing the laser fluence and scanning speed. Clear and uniform HSFLs were formed over the entire ablated area when the laser fluence and scanning speed were 89[math]mJ/cm2 and 0.01[math]mm/s, respectively. The duty cycle of the HSFL was measured to be as high as 0.36, and the thickness of the HSFL layer was found to be in the range of 409–546[math]nm. The phase retardation of the FTO film with HSFLs could reach up to 96[math]nm and could be used as an optical attenuator with a tunable range of 71–100% for 532[math]nm linear polarized light.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
In this paper, we propose a hybrid amplifier-based 8-port Cross-Polarization Modulation (XPoM) interconnection with low polarization sensitivity unlike conventional Semiconductor Optical Amplifier (SOA)-based switching. The three-stage configuration utilizes Erbium-Doped Fiber Amplifier (EDFA) as an intermediate stage to reduce the effects of inherent polarization modulation creating large Transverse Electric – Transverse Magnetic (TE–TM) relative phase shifts. The appreciable error rate of [math] and Extinction Ratio (ER) of 14.166 dB have been obtained with 100 GHz of port-spacing at different input powers. The low Polarization-Dependent Loss (PDL) of 1.0045 dB, small variations of azimuth and ellipticity with device angle in S–E–S configuration in contrast to that of SOA, adds to the superiority of the proposed model.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
We investigate the effect of temperature on Manakov solitons in biased photorefractive crystals having both linear and quadratic electro-optic effects simultaneously. Two different physical quantities, namely, the dielectric constant and the dark irradiance, have a temperature dependence which in turn affects the Manakov solitons. We consider three realizations of the Manakov solitons for our present analysis, namely, the bright–bright, dark–dark and bright–dark Manakov soliton pair. The existence curve and its modification due to temperature has been studied in detail for each of the Manakov soliton pair. A comprehensive investigation of the functional dependence of the soliton width with temperature is undertaken for different parameters like beam intensity and external electric field for each of the Manakov soliton pair. The tuning of photorefractive soliton characteristics by changing of temperature has potential practical applications in optical networks and optical waveguiding.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
Nematicons became a key topic of interest in liquid crystal technology in recent years. This paper contributes in understanding the fantastic features of nematicons in optics and further disciplines. This piece of research investigates nematicons for obtaining various exact solutions for Kerr and non-Kerr law nonlinearities with the help of the Kudryashov’s approach and the tanh–coth technique. The acquired outcomes involve rational, periodic and hyperbolic solutions as well as their combo-type solutions for all the four cases of nonlinearity. A comparative study is conducted to show the novelty of present results with results already existing in the literature. The constraint conditions obtained ensured that the existence of these solutions is extraordinarily favorable to further investigate the dynamics of nematicons for various kinds of nonlinearity. The dynamics of the few of the obtained solutions are also discussed by 3D plots.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
In this paper, we theoretically analyze optically-induced transparency and absorption properties of a weak probe field in a two-mode coupled micro-cavity system and explore the tunable asymmetric Fano line shape of the transmission rates of the probe field. Both the modes in our system consist of an optical Kerr medium, one of them being passive while the other mode can be either active or passive. The forward transmission and backward reflection profile of the probe field are investigated for both passive–passive and passive–active cavity systems by varying different system parameters such as probe field detuning, photon tunneling strength, gain-to-loss ratio, etc. The results of this study have the potential to be applied in construction of quantum telecommunication and photonic devices.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
In recent trends, digital systems in the light of power dissipation are a crucial issue. In computing, the computational process of reversible logic is bijective and can decrease the rising issue of power dissipation. In reversible circuit design, Peres gate considered as one of the fundamental reversible gate. Therefore, a Peres gate using Add/Drop Multiplexer (ADM) and Reflective Semiconductor Optical Amplifier (RSOA) is proposed in this paper. Frequency encoding scheme and dibit-based logic are incorporated here. In long range transmission, frequency encoding bears huge benefits in respect with the other encoding techniques. This encoding technique may decrease the probability of bit error. Due to the high gain and low noise property of RSOA, the proposed design can perform operations like computation, data processing, etc. at ultra-high speed with low noise. MATLAB Simulink (R2018a) software has been used to verify the operation of the proposed design.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
Single crystals of zinc sulfate doped L-alanine (LAZ) were grown by adopting the slow evaporation technique at room temperature. The crystal structure of LAZ was determined using single-crystal X-ray diffraction. The functional groups of LAZ were identified by FT-IR spectroscopy analysis. UV–Visible–NIR transmittance study was carried out, and the bandgap energy was found. A fluorescence study was performed to get the emission spectrum of the LAZ crystal. The Vickers microhardness test is used to determine the LAZ crystals mechanical behavior. Thermogravimetric and differential thermal analyses have also been studied to investigate the thermal property of the LAZ crystal. The efficiency of the title crystal’s second harmonic generation (SHG) was investigated. The electrical properties were estimated by impedance study.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
We have numerically generated the rogue waves supported by discrete nonlinear Schrödinger equation (DNLSE). The investigation has been made on pure cubic DNLSE as well as on cubic-quintic discrete nonlinear Schrödinger equation (CQDNLSE). Runge–Kutta fourth (RK4) order method has been employed to obtain these results. For the cubic DNLSE breathers are found to be localized in one of the dimensions and periodic in the other dimensions, whereas rogue waves are found to be appearing from nowhere and disappearing without a trace. For CQDNLSE it is reported that the sign of quintic term possesses a significant effect on the intensity of the rogue waves. Further these waves are appearing from nowhere but instead of disappearing these show periodic reappearance. For larger value of quintic coefficient this phenomenon is visible at shorter length scale. Breathers are reported for the first time for the cubic DNLSE. The obtained results for CQDNLSE are unobserved previously in any constant coefficient discrete nonlinear equation.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
MAPbBr3 quantum dots in SiO2 mesopores ([math][math]nm) were prepared by the spin-coating method, and their luminescence and nonlinear optical properties were studied by time-resolved photoluminescence (TRPL) and Z-scan techniques. The results showed that the absorption and photoluminescence peaks are at 464[math]nm and 476[math]nm, respectively. The TRPL spectroscopy showed two relaxation processes, a short lifetime (1.04[math]ns) and a long lifetime (4.49[math]ns), attributed to the trap–capture recombination and the electron–hole radiative recombination, respectively. Two-photon absorption (TPA) coefficient was 529[math]cm/GW at 800[math]nm. The nonlinear signal changed from TPA to saturable absorption with increase in light intensity.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
In fifth-generation (5G) fronthaul networks, the wavelength division multiplexing passive optical network (WDM-PON) is considered as an important tool to address the advanced transmission requirements. The nonlinear effects occur when multiple wavelengths are transmitted simultaneously in the same optical fiber. In this paper, we investigate the four-wave mixing (FWM) and the cross-phase modulation (XPM) effects by using non-return-to-zero (NRZ), 4-level pulse amplitude modulation (PAM4), and optical duobinary (ODB) modulation formats in WDM-PON-based 5G fronthaul networks. The results show that ODB performs better when it comes to limiting the FWM and XPM effects because of its precoded attribute. Compared to the unpredictable sensitivity penalty based on NRZ and PAM4, the FWM-induced sensitivity penalty using ODB is reduced to 2[math]dB. Moreover, the XPM-induced sensitivity penalty is measured as 1[math]dB by adopting ODB, which is almost 5[math]dB better than NRZ and PAM4 modulation formats.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
The single crystalline diethyl 3,3[math]-[(2,4-dichlorophenyl)methylidene]bis(1H-indole-2-carboxylate) (D32DMBC) samples are fully grown-up in a proper and in a successful manner by the prevailing slowly evaporating methodology. The lattice cell frameworks by XRD modus operandi also corroborated that the D32DMBC crystal system is monoclinic in nature. The structural properties by a conceptual way authenticate the elucidation and also the proper vindication for bond parameters. The nano influx is 3.2768 micron and the film-coated influx of 2.9977 microns as a mid-value between the macro as well as the nano assessment is suitable for electronic filters by D32DMBC crystals, and also used for tribological-coated utility as well as in frequency multipliers. Diabetes mellitus is the repetitive disease in the way of life and sustaining approach of D32DMBC — organic crystals are properly, accurately experimented by the use of the software pertaining to the D32DMBC by docking effect. The affinity inhibitory activity of A74DME and exploratory molecule of D32DMBC are [math]8.1[math]kJ/mole and [math]8.4[math]kJ/mole correspondingly. The computational effect of Hirshfeld portrays the internal/external fields as well as the electron higher/lower profile in the shape index proviso for optical utility identification and proper electronic utility.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
In this paper, we report the significance of the double Stokes–Mueller polarimetry (DSMP) technique, to characterize a large size ([math][math]mm) Potassium titanyl phosphate (KTP) crystal. The crystal undergoes second harmonic generation with type II phase matching. The study of standard KTP crystal using the DSMP technique helps to validate the efficiency of this technique. We were able to extract the crystal’s double Mueller matrix, relative contribution of the susceptibility tensor components, the phase difference between the susceptibility tensor components, etc. We could determine the crystal axes orientation using this optical technique, which was not possible through a single crystal X-Ray diffraction technique for such a large size crystal for which both optic axes and crystallographic axes are the same. Axes direction determined from polarization microscope measurements and Laue diffraction measurements on KTP crystal is compared with those obtained from DSMP measurements.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
This paper explores the new [math]-dimensional nonlinear Schrödinger equation which is used to model the propagation of ultra-short optical pulses in highly-nonlinear media. This equation is newly derived based on the extended [math]-dimensional zero curvature equation. An effective technique, namely, the extended sinh-Gordon equation expansion method is applied to find optical soliton solutions and other solutions for this model. As a result, dark, bright, combined dark–bright, singular, combined singular soliton solutions, and singular periodic wave solutions are obtained. The stability of the model is investigated by using the modulation instability analysis which guarantees that the model is stable and all solutions are stable and exact. Physical explanations of the obtained solutions are presented by using 3D and 2D plots. The reported outcomes are useful in the empirical application of fiber optics.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
In this work, we perform a theoretical analysis of the electronic and optical properties of CdS quantum dot (QD) encapsulated in ZnSe matrix. The intersubband energy levels and the matching wave functions are calculated using the effective mass approximation (E.M.A) and the compact density matrix approach. The effect of self-energy contribution due to the charging of CdS QD with ZnSe matrix has been taken into account from the beginning. We found that the linear and nonlinear optical properties are considerably impacted by the size parameter and the optical intensity [math]. The results obtained have essential consequences for the design of optoelectronic and photonic devices.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
In this study, three well-known partial differential equations (PDEs) are extended to their logarithmic nonlinearities with and without attenuation terms. These new models are the logarithmic unstable nonlinear Schrödinger (UNLS), the logarithmic Hamiltonian amplitude, and the logarithmic extended UNLS equations. As a result, the new logarithmic equations are investigated to find their Gaussian solitary waves (GSWs). The GSW solutions are presented for all new logarithmic models. Furthermore, we demonstrated that all logarithmic models are distinguishable by GSWs. These logarithmic extensions and their Gaussian solutions will be useful to find logarithmic extensions of other PDEs.

Abstract: Journal of Nonlinear Optical Physics & Materials, Ahead of Print.
In this paper, features of generation of two types of surface plasmon-polaritons (SPPs) in optical anisotropic hyperbolic metamaterials formed by a periodic lattice of metal nanocylinders embedded in a dielectric matrix are considered. The dependencies of the group velocity and the penetration depth inside metamaterial of the generated plasmon-polaritons on filling ratio are established and analyzed. Based on the effective medium theory, the surface plasmon-polaritons generation at interface of hyperbolic metamaterials is analytically calculated and discussed.
