Abstract: In this paper, we propose to implement an all-optical XOR gate for 160 Gb/s return-to-zero data signals using a single quantum-dot semiconductor optical amplifier (QD-SOA) assisted by a ...

Golden Gate Park, one of the top tourist attractions in the United States, sees an estimated 24 million visitors from around the world every year. All those people make for sizable amount of ...

Abstract: We propose and demonstrate an all-optical XOR gate at 20 Gb/s using four-wave mixing in a semiconductor optical amplifier (SOA), with return-to-zero differential phase-shifted keying ...
