Abstract :
A circuit model for multimode bistable laser diodes (BLD) has been developed from the rate equations. The model is simulated for dc sweep and transient conditions using circuit simulation program PSPICE. The hysteresis behaviour and the dynamic properties of the longitudinal modes of the BLD are studied. The dc sweep simulation shows "S"-shaped bistability for the fundamental mode, whereas the sidemodes exhibit a "loop"-like bistability. The transient simulation also shows similar behaviour.
