Controlling the bistability and self-pulsation characteristics of two-segment bistable laser diode based on delayed optoelectronic feedback

Abstract

In this paper, the delayed optoelectronic feedback is introduced to the absorption region in order to control the bistability and self-pulsation characteristics of the two-segment bistable laser diode (TBLD). The rate equations have been used to model numerically the effects of feedback gain and delay time. The result s show that the stable region of TBLD varies periodically with the delayed time; the bistable region shrinks with increasing delay time; the stability can beenhanced at certain values of delayed time, and the instability can be reached more easily for negative optoelectronic delayed feedback.
