Ultrahigh-speed All-Optical Wavelength Conversion for PolSK Signal Based on Parallel Dual-Pump FWM in SOA

摘要

We propose an ultrahigh-speed all-optical wavelength conversion for polarization-shift-keying (PolSK) signal, based on parallel dual-pump four-wave mixing (FWM) in a semiconductor optical amplifier (SOA). A comprehensive broad-band dynamic model of this kind of all-optical wavelength converter is developed. By numerical simulation, using the broad-band dynamic model, the effects of input waves powers and wavelengths on the output performance of wavelength conversion for PolSK signal are theoretically investigated in detail. This scheme is suitable for wide wavelength range of input PolSK signal. It is simple, compact, and feasible for ultrahigh-speed operation.
