Paper Abstract

Optical memory is a very important component in all-optical information systems. Optical flip-flop memories have already been shown to be the essential elements for all-optical packet switching. Semiconductor ring laser (SRL) as a digital photonic device has received much more attention recently. With external optical injection, SRL can be switched from one direction to another due to its directional bistability providing potentially very abrupt responses to input optical signals. SRL can also be integrated with other optical devices to form functional photonic integrated circuits (PICs). Therefore, an optical static random access memory (SRAM) cell using an integrated SRL set-reset flip-flop (SRFF) device to perform a single bit memory function is proposed and constructed. Read and write operation at 1Gb/s are achieved with extinction ration >10dB.
