Characterization of Wideband Semiconductor Optical Amplifiers based on OptiSystem and MATLAB

Abstract

A study about different types of semiconductor optical amplifiers (SOA)s-linear, nonlinear and in-line SOAs modelling is carried out. The SOA key performance characteristics covered in this paper include optical gain, power, and amplified spontaneous emission (ASE) noise figure. These characteristics definition are included in this work together with the tabulation of each SOA specification parameter operating in the operational conventional (C-) band. The first modelling of SOA wideband travelling wave (TW) component is done through a simple configuration using OptiSystem software. Next, the second modelling method is simulated through numerical steady-state model using MATLAB software. Each graphical result is explained and discussed according to the operational characteristic theories of SOA along with the evaluation for the best performance among the types of SOAs. The contrasted result among them had shown that linear SOA has the most ideal and competitive characteristics, as compared to the nonlinear and in-line SOAs, especially a better choice as gain medium in the multiwavelength fiber laser (MWFL) application.

Dynamics and its Effects on Saturation Region in Semiconductor Optical Amplifiers

“…So many amplifiers invented to make this happen from the bulk semiconductor-optical amplifier (SOA) [1]. Travelling wave-SOAis considered one of the most important devices because it has main characteristics, such as little size, highly gain, wide gain bandwidth, and the capability to be integrated in the cost effective way [2,3]. The bulk SOA origin began after evolution for the Fabry-Perot -cavity that utilized into an evolution of the lasers.…”

Performance Investigation of Dual Wavelength Fiber Laser using different SOAs

“…The main benefit of using SOA in MWFL is that it has the property of inhomogeneous gain broadening to alleviate the issue of mode competition that is commonly present in the generation of multiple lasing wavelengths at room temperature [10][11][12][13]. Low mode competition in SOA is a significant advantage over erbium-doped fiber amplifiers (EDFAs), where the number of laser modes is generally limited because of high mode competition resulting from the homogenous gain broadening of erbium ions.…”
