Abstract
Several dynamics of directly modulated InAs/InGaAs quantum
dot semiconductor laser in the presence of optical feedback have been studied extensively. The effect of feedback strength,linewidth enhancement factor, dc bias strength of the injection current, the modulation strength and modulation frequency are studied. Various types of dynamics ranging from periodic to chaotic ones are seen to occur. Coherence collapse (output drop out) occurs as a result of choosing certain combinations of the control parameters appeared in the theoretical model.
