Abstract :
The integration of multi-mode interference (MMI) bistable laser diodes (BLDs) with distributed Bragg reflectors (DBRs) is analyzed for cascadable all-optical flip-flops. Device behavior in terms of side mode suppression ratio (SMSR), extinction ratio, and power-current relation is discussed for varied mirror parameters for a 1.55-μm InP/InGaAsP ridge structure. The static laser characteristics are determined through the beam propagation method (BPM) in conjunction with the laser carrier rate equations.
