Three-input Ultrahigh-speed All-optical AND and NOR Gates Based on Orthogonal Dual-pump Four-wave Mixing in Semiconductor Optical Amplifier With PolSK Modulated Signals

摘要

Ultrahigh-speed all-optical AND and NOR gates for three-input polarization-shift-keying (PolSK) signals, based on orthogonal dual-pump four-wave mixing (FWM) in semiconductor optical amplifier (SOA), is proposed and theoretically investigated, This scheme is simple, compact, and feasible for ultrahigh-speed operation.
