In this paper, we propose and experimentally demonstrate a novel all-optical XOR gate using bistable SRLs. This is the first report to our knowledge that all-optical logic XOR gate is realized using the monolithically integrated bistable semiconductor ring lasers. In this initial experiment, we focus on demonstrating the novel principle of operation and logic XOR function that can be realized with...
The modulation bandwidth of a optical injection-locked (OIL) master-slave configuration using a semiconductor ring laser (SRL) as the slave laser is investigated. The modulation bandwidth depends on the detuning frequency, input optical power into the slave SRL, and the bias current to the SRL in the master-slave configuration. Modulation bandwidth of >40 GHz has been achieved when modulating the...
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.
