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 ...

Abstract: All-optical logic gate based on parametric processes in periodically poled lithium niobate (PPLN) waveguides is a promising technique in future high-speed all-optical signal processing. A ...
