We investigate optical bistability of an injection-locked single-mode Fabry-Perot laser diode. Normal and reversed optical bistability curves are observed from the injection-locked laser. And the inverse bistability is used to implement an all-optical flip-flop with the high on-off ratio of over 35 dB.

All-optical flip-flops (AOFFs) using optical bistability of injection-locked Fabry-Perot laser diodes (FP-LDs) are demonstrated. To increase performance of the AOFF, single-mode FP-LDs are introduced. The single-mode FP-LD is used as an auxiliary beam source that sustains the state of AOFF or it is used as a state memory component itself to increase an on-off contrast ratio up to 35 dB.

We demonstrate all-optical flip-flop operation based on the bistability injection locked FP-LD. The proposed all-optical flip-flop consists of a slave FP-LD and a specially designed single mode FP-LD.
