“…e use of WDM technology in optical transmission systems and their related optical networks affects the performance of optical systems. However, it can be clearly noticed from Figures 12 and 13 that, in the proposed model, the 16 transmitted wavelengths keep a high reflectivity with a low side lobe level and narrow FWHM, which further demonstrates the effectiveness of the proposed model [11].…”

“…Four-Wave Mixing (FWM), Stimulated Raman Scattering (SRS), and Cross-Phase Modulation (XPM) are the most dominant types of nonlinear effects that have been generated due to the optical amplification and limit the performance of optical transmissions [8][9][10]. Many numerical methods have been proposed to compensate the chromatic dispersion and reduce the nonlinear effects in optical fiber transmission systems [4,11,12]. In this work, we propose a new optical transmission model to improve the performance of WDM optical transmission systems using Fiber Bragg Grating (FBG) and EDFA based on the Split-Step Fourier Method (SSFM).…”

In this paper, a new optical transmission model was investigated and developed in order to improve the performance of Wavelength Division Multiplexing optical transmission systems. For this purpose, an efficient theoretical method combining a Fiber Bragg Grating (FBG) and Erbium Doped Fiber Amplifier (EDFA) was implemented. Enhancements on the transmitted signal amplitudes with important compensation of the chromatic dispersions and large reduction on the nonlinear effects were obtained. The reflectivity peak, the full width at half maximum bandwidth, and the side lobe level have been studied in depth to demonstrate the efficiency of the proposed method. To apply the new method, we considered a complicated system of 16-channel wavelengths, where the split-step fourier method was used to solve the nonlinear Schrödinger equations, and the transfer matrix method was applied to describe the coupled mode equations. The wavelengths corresponding to different values of reflectivity peaks calculated previously in the FBG outputs section were injected as EDFA inputs to determine the output power and the gain of the new transmission system. All results are analyzed using Matlab program.

The apodization function has a significant impact on the state of the art of group delay, dispersion compensation, and acceptable decrease in side lobes in the spectrum of Fiber Bragg Grating (FBG) reflection. Accordingly, the Bragg grating length would be considered the backbone parameter in order to achieve a distinguishable performance. Here, the utilization influence of the presence of FBG is considered a dispersion compensator. In addition, we have implemented a tuned uniform-apodized FBG methodology according to various apodization functions. Common apodization functions have been studied and tested effectively. Experimental results show that the proposed raised cosine apodized function has scored the highest reflectivity with 50% reduction in the side lobe level and the narrowest bandwidth among all tested functions. Moreover, simulations for this function were performed with various lengths of grating. It is demonstrated that the reflection spectrum value is fixed at 100% at grating lengths greater than or equal to 28 mm and the minimum dispersion value is realized.
