Abstract

We demonstrate a novel optical flip-flop configuration which consists of one Fabry-Perot laser diode (FP-LD) and two Fiber-Bragg-Gratings (FBG).The all-optical flip-flop is realized based on the optical bistability of injection-locked single-mode of FP-LD. The essential part to obtain bistability in this system is that the output of FP-LD is fed back partly by two FBGs at certain wavelengths. The EDFA was used to adjust the power of feedback beam. The on or off state of the All-optical flip-flop is determined by the set or reset light externally at different wavelength. The all-optical flip-flop operated at the wavelength of 1537nm with on-off contrast ratio of 15 dB. The theory and experimental result are presented.
