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.
