  • The Impact of Dysprosium Ions as a Dopant on Linear and Nonlinear Optical
           Dispersion Parameters in a-Se Thin Film

    • Abstract: Publication year: 2018Source: International Journal of Optoelectronic Engineering, Volume 8, Number 1Fathy A. Abdel-Wahab, Heba Abdel MaksoudThin films of un-doped and doped a-Se with Dysprosium rare earth ions have been prepared by thermal evaporation technique. The optical transmission spectra of the investigated films have been measured in a wide spectral range and used to calculate the linear optical constants together with the optical energy gap of studied films. The observed decrease in the values of the energy gap against the increase of the Dysprosium (Dy) content in a-Se films has been explained using Mott and Davis Model and in terms of electronegativity difference of the constituent atoms. Furthermore, the dispersion of nonlinear parameters such as second order refractive index and nonlinear absorption coefficient (two-photon absorption coefficient) of investigated films are presented and discussed.

  • State of Fiber Optic Networks for Internet Broadband Penetration in
           Nigeria - A Review

    • Abstract: Publication year: 2017Source: International Journal of Optoelectronic Engineering, Volume 7, Number 1Oboyerulu Edevbie Agboje, Simon Oluwatimilehin Adedoyin, Charles Uzoanya NdujiubaInternet broadband penetration has increased globally as a result of various fiber optic technologies employed. Nigeria fiber optic network is massive and very enterprising because the nation has great potentials in utilizing Internet broadband bandwidths as the largest Black Country in the world. The country presently has active submarine fiber optic cables connecting the country to the world through Europe with huge Internet broadband capacities. However, the Internet broadband penetration in the country is still very low with about 10% of the Oceanic Optical fiber capacities utilized and just 6% of fiber optic broadband penetration. This paper reviews the present state of fiber optics Internet broadband network penetration in Nigeria looking at the spread of fiber optic networks in the country, the application of the fiber optic technologies and the challenges of deploying fiber optic technologies for Internet broadband penetration in Nigeria. The paper classified the fiber optic network in Nigeria into the core, the backbone/backhaul and the access/last-mile fiber optic networks. The core fiber optic network is the oceanic fiber optic from Europe and Cameroun while the backbone fiber optic network is the fiber to the states and to central offices/ISPs. The access/last-mile fiber network is the fiber optic to the base transmission stations and the end users. It can be deduced from this paper that the last mile fiber optic network in the country is still very low and over 99% of the Internet penetration in the country is through the wireless mobile phones.
       
  • Performance Analysis of Erbium Doped Fiber Amplifier’s and FWM
           Characteristics in a Passive Optical Network

    • Abstract: Publication year: 2016Source: International Journal of Optoelectronic Engineering, Volume 6, Number 1Franklin Ajibodu, Zacchaeus Adetona, Babajide OjoAs optical network system become more complex and hence expensive, hands-on experiments based on optical network simulation have become very important for teaching in technical and technological institutes. This study investigates the performance of the optical network under different scenario with a minimum cost. An experimental study using OptiWave OptiSystem simulator to observe the performance of Erbium Doped Fiber Amplifier (EDFA) and determine its characteristic under varying input power at 1550nm range was carried out. It further demonstrated the performance of EDFA under dense wave division multiplexing (DWDM) by observing its characteristics when using four transmitter with wavelengths 1560nm, 1550nm, 1541nm, 1532nm multiplexed over a fiber link and amplified by an EDFA. In a further experiment in this study, the effect of Four Wave Mixing (FWM) amplified over a DWDM network was observed, and by extension the effect of reducing the Chromatic dispersion coefficient from 16.75ps/nm/km to 11.75ps/nm/km on the FWM formed was shown. The result obtained showed that for an EDFA to be used as an amplifier the amplified spontaneous emission (ASE) characteristic of the EDFA must be low in order to obtain a high Optical signal to noise ratio (OSNR). It was also observed from the eye diagram obtained that the inter symbol interference (ISI) was reduced at wavelength of 1541nm and 1532nm due to lower attenuation at this range. The result also showed that the effect of FWM increased with increase in input power at the transmitter and by increasing the chromatic dispersion coefficient, the effect of FWM on the output wave transmitted was reduced.
       
  • Temperature Effect towards DFB Laser Wavelength on Microwave Generation
           Based on Two Optical Wave Mixing

    • Abstract: Publication year: 2015Source: International Journal of Optoelectronic Engineering, Volume 5, Number 2Nursidik Yulianto, Bambang Widiyatmoko, Purnomo Sidi PriambodoSemiconductor laser can be implemented in various fields, such as for telecommunication, radar, spectroscopy and sensor. Specialized for radar application, laser can be applied to generate microwave with heterodyne technique by mixing two laser sources. In this application, the quality of the laser wavelength stability is crucial in order to generate stability desired microwave source. In some studies it has been reported that the change of temperature causes the wavelength changes linearly. In our experiment, it is proven that the increase in temperature causes a shift in the peak wavelength toward the long wavelength laser typical of 0.094 nm/°C. Theoretically, it is shown that the wavelength shift caused by the thermal expansion on the laser grating period. In addition to the shift in wavelength, it is also shown that the increase in temperature causes a decrease in the optical power at the laser output. From the experiments of mixing two lasers that we have conducted, it was found that the tunability factor of laser beat frequency versus temperature is 10.35 GHz/°C. In this paper we show that the beat frequency of the result of mixing two laser diodes can be tuned by varying the temperature of one laser by varying Peltier temperature and laser injection current and let the other laser constant.

           Nanostructures with Low Conversion Efficiency for Exploring Solar Energy
           Concepts

    • Abstract: Publication year: 2015Source: International Journal of Optoelectronic Engineering, Volume 5, Number 1Haruna Isah, Danladi Eli, Gyuk P. M.We developed an organic dye sensitized solar cell with TiO2 nanostructures integrated into the photoanode. The sensitizer in this research paper was extracted from flame tree flower (delonix regia) and pawpaw (carica papaya) leaves respectively. The flame flower was separated from its stalk. Each of the samples was crushed separately via the use of a porcelain mortar and pestle. The samples, each was filtered and stored in test tubes. The filtrate (extract) is the dye solution for sensitization. The dye is chemically connected to a porous layer of a wide band-gap semiconductor. The DSSCs employing the nanocrystalline TiO2 as photoanode showed a power conversion efficiency of about 0.0051%.
       
  • Interferometric Estimation of Nonlinearity in GRIN Optical Fiber

    • Abstract: Publication year: 2015Source: International Journal of Optoelectronic Engineering, Volume 5, Number 1Fouad El-Diasty, H. A. El-Hennawi, Mona A. SolimanIn many industrial applications, coupling high power laser beam into multi-mode graded-index fiber (GRIN) is an important issue especially when deeper penetration and speed cutting/welding processes are required. With increasing the laser power, nonlinear effects such as self-focusing takes place leading to a catastrophic damage for optical fibers. Construction of robust high power fiber-laser systems still need to analyze the different parameters that affect the nonlinear response of the fiber material and its waveguiding conditions. Due to its high spatial resolving power, interferometry is used to study the efect of waveguide and material dispersion profiles, and the central core-index dip on the Kerr nonlinear index profiles of GRIN fiber.
       
  • Analysis and Applications of Nonlinearities in Optical Fibres in
           Wavelength Division Multiplexed Systems

    • Abstract: Publication year: 2015Source: International Journal of Optoelectronic Engineering, Volume 5, Number 1Charles Uzoanya Ndujiuba, Samuel Ndueso JohnOptical nonlinearities play a major role in optical fibre with respect to transmission capacity and performance of the system. This degrades the system performance, especially in wavelength division multiplexing (WDM) systems, where several channels co-exist in the same fibre and propagating simultaneously, resulting in high optical intensities. They can result in pulse distortion referred to as self phase modulation (SPM), cross phase modulation (XPM), crosstalk between channels, and four wave mixing (FWM). However, these non-linearities also have many useful applications, especially for the implementation of all-optical functionalities in optical networks. In this paper, we briefly review the different kinds of optical nonlinearities encountered in fibres, identify the essential materials and fibre parameters that determine them. The paper simulates two channel WDM optical communication systems in single mode fibre over long haul of 100 km to investigate the effect of SPM, XPM and FWM. Their thresholds, managements and applications are also discussed; and comparative study of these effects is presented.
       
  • Optical and Electrical Properties of CdO: Sn Thin Films for Solar Cell
           Applications

    • Abstract: Publication year: 2014Source: International Journal of Optoelectronic Engineering, Volume 4, Number 1N. E. Makori, I. A. Amatalo, P. M. Karimi, W. K. NjorogeTin doped Cadmium Oxide (CdO:Sn) thin films were successfully deposited by thermal evaporation in the Edward’s Auto 306 Magnetron Sputtering System. Their optical and electrical properties were studied using Solid Spec-3700 DUV Spectrophotometer and Four Point Probe respectively. The optical properties of CdO:Sn thin films showed high transparency in the visible region of the electromagnetic spectrum which varied with Sn doping, this makes CdO:Sn an excellent candidate for optoelectronic applications such as a window layer. Undoped Cadmium Oxide (CdO) thin films were also prepared for comparison with tin doped Cadmium Oxide thin films. Doped and undoped Cadmium Oxide had a transmittance of 70-85% and 50-89% respectively. Band gap energy for undoped CdO was 2.43eV while that of tin doped CdO ranged between 3.19-3.29eV for tin doping of 1-7%. Resistivity of undoped and Tin doped Cadmium Oxide ranged between 16-93Ωcm.
