Optical bistability and optical storage based on injection locked Fabry-Perot semiconductor laser

All-optical bistability based on injection locked Fabry-Perot semiconductor laser (FP-LD) and its application in all-optical storage are studied in this paper. Injection locking of FP-LD is experimentally studied in this paper. The output power characteristic of injection locked FP-LD is analyzed experimentally, showing that threshold width of hysteresis loop and the extinction-ratio are influenced by the difference in the injection optical-wavelength detuning. Furthermore, 2.5 GHz optical storage with 10 Gb/s input signal is realized by reasonably setting the control signal power. The feasibility of implementing high-speed all-optical storage is verified by using the injection locked FP-LD, which shows great applicability to the field of high speed optical fiber communication.
