Paper Abstract

We propose and demonstrate 40Gb/s multifunctional all-optical logic gates based on single semiconductor optical amplifier (SOA) and a blue shifted optical bandpass filter (OBF), suitable for both return-to-zero (RZ) and nonreturn-to-zero (NRZ) format. The logic functions NOT, NOR and OR of RZ format are realized at the OBF detuning of -0.15nm, - 0.22nm, and -0.44nm, respectively. The logic functions NOT and NOR of NRZ format are realized at the OBF detuning of -0.24nm. The measured ER is around 7dB and Q factor is over 6. Our scheme has the potential advantages of multilogic functions, simple structure, and high tolerance to input pulsewidth.
