Wu Yang, Li Peili, Shi Weihua. An FWM-based all-optical wavelength converter appropriate for polarization shift keying modulation. [J]. (2):37-39(2010)
An all-optical wavelength converter scheme appropriate for Polarization-Shift-Keying(PolSK) is proposed on the basis of the Four-Wave Mixing(FWM) effects in Semiconductor Optical Amplifiers(SOA).Injecting complementary light can shorten SOA gain recovery time
while amplifying saturated power improves the wavelength converting efficiency.This all-optical wavelength converter is theoretically implemented in numerical simulation and the effects of input pump light
signal light and complimentary light on the output properties of the converter are investigated.
