OPTICAL-INJECTION EFFECTS AND ALL-OPTICAL SET-RESET OPERATIONS IN 2-SEGMENT STRAINED MULTI-QUANTUM-WELL DISTRIBUTED-FEEDBACK BISTABLE LASERS

Optical injection effects and all-optical set-reset operations in two- segment strained multiquantum-well (MQW) distributed feedback (DFB) bi stable lasers were experimentally investigated. The optical bistable c haracteristics under detuned optical injection, of strained MQW DFB bi stable lasers, show the effect of the residual Fabry-Perot side modes of the DFB structures; optimizing the input wavelength and the input p ower is suggested for applications. The switching properties of dynami c optical set-reset operations with pulsed optical injection were repo rted, which appear to be related to the optical bistable characteristi cs under cw optical injection; however, the switching transients are f ound to essential to full understanding of these switching properties.
