This paper demonstrates the measurements of direct modulation bandwidth of a bistable racetrack semiconductor ring laser. It is exhibited using the phenomenon of optical injection-locking in the master-slave layout. Semiconductor ring laser is employed as the slave laser. Modulated signal is injected at 1530 nm, which is about 20nm away from the main lasing mode. The frequency response of the main...
This paper proposes and demonstrates an all-optical static random access memory (SRAM) cell using a bistable semiconductor ring laser set-reset flip-flop integrated with four SOAs at each output. Read and write operation at 1Gb/s are achieved with extinction ration ≫10dB.
This paper describes all-optical digital logic AND and XOR gates based-on cavity-enhanced four-wave-mixing in an integrated semiconductor ring laser at 2.5Gb/s. Error free operation with extinction ratio higher than 10dB is achieved.
