Abstract

We focus on studying the dynamics of bulk semiconductor optical amplifiers and their effects on the saturation region for short pulse that differ, however there is the same unsaturated gain for both dynamics. Parameters like current injection, fast dynamics present by carrier heating (CH), and spectra hole burning (SHB) are studied for regions that occur a response to certain dynamics. The behavior of the saturation region is found to be responsible for phenomena such as recovery time and chirp for the pulse under study.

Highlights

In a long distance optical communication system, when the signal force becomes low, we need to boost up it
A researcher's attention increased to semiconductor-optical amplifier (SOA) because it has a non-linear feature, we focus to one feature that included the study of the output power against input power which that clearly referred to the saturation power region under consideration
Sci. 34(4)2021 electrically pumped for supply electrons to the active area [6]. It has two types: the first is Fabry-Perot amplifier and the second travelling-wave amplifier [7,8].SOA has many parameters like gain, the noise figure, saturation output power, gain bandwidth, and recovery time, and other parameters of ultrafast-dynamics such as carrier heating (CH) and spectra hole burning (SHB), which are used to determine the performance of the amplifier and to control the output performance.These parameters have a signifcant influence on the saturation region[9,10,11,12]

Summary

Introduction

In a long distance optical communication system, when the signal force becomes low, we need to boost up it. SOAs are almost like semiconductor-lasers into which they need a gain area that is. Sci. 34(4)2021 electrically pumped for supply electrons to the active area [6] It has two types: the first is Fabry-Perot amplifier and the second travelling-wave amplifier [7,8].SOA has many parameters like gain, the noise figure, saturation output power, gain bandwidth, and recovery time, and other parameters of ultrafast-dynamics such as CH and SHB, which are used to determine the performance of the amplifier and to control the output performance.These parameters have a signifcant influence on the saturation region[9,10,11,12].
