Abstract

In this work a systematic study on Close-Loop System occurring in the rout to chaos observing in integrated of quantum dot semiconductor lasers with optical feedback. The time delay of the feedback has been chosen in order to provide suitable condition for intermittent dynamics. The effect of long and short external cavity of QDSL on synchronization in a closed-loop system are studied under an enhancement factor of (α=3.5) value by solving the set of 6-rate equation.
