Abstract :
Integrated all-optical logic gates that exploit the optical gain quenching effect in laterally optically pumped semiconductor multi-section edge-emitting lasers (SMEELs) are described. An accurate 2D time-domain (TD) model was solved using an FFT based BPM that was implemented to investigate the gates´ gain, modulation depth, and speed. Lasers with optical gain control capable of routing and logic functions are demonstrated via the gain quenching effect.
