Optical S-R latch demonstration using injection-locked single-mode FP-LD

An optical S-R latch is demonstrated using two injection locked single-mode (SM) Fabry-Perot laser diode (FP-LD). The S-R latch is based on the bi-stability and injection-locking properties of FP-LD. The latch performs simultaneous inverted and non-inverted outputs in set and reset states. The switching time was about 90 ps.
