THEORETICAL STUDY OF QD SEMICONDUCTOR LASER DYNAMICS UNDER OPTICAL FEEDBACK

In the present work, we study the dynamics of QD semiconductor laser under optical feedback such as the time behavior of the carriers in wetting layer, the output photons intensity and Occupation probability for the QD active region. When studying the effects of these variables the dynamics are more complex when increasing the optical feedback strength and linewidth enhancement factor at different values of time delay. These dynamics are appeared the nonlinearities and chaos behavior output of laser and these results agree with other results of other researches
