Modélisation Physique du Bruit Relatif d'Intensité et du Bruit de Phase des Lasers à Semi-conducteurs

Abstract

This work aims to study the modeling of relative intensity noise (RIN) and phase noise of semiconductor lasers. It consists of two parts. The first part provides an overview of semiconductor lasers. The second part is dedicated to studying the effect of physical parametres of the lase such as current ,modulation frequency, threshold gain, and linewidth enhancement factor on the noise and optimal parametres of semiconducteur lasers (resonance frequency,maximum RIN, and RIN limit).It has been shown that the laser parametrs play a cruciel role in the optimal performance of semiconductor lasers. Th derivation of phase noise,and linewidth of laser emission is also addressed and discussed in this section
