A High Efficiency Wavelength Conversion Scheme Based on Four Wave Minxing in a Semiconductor Optical Amplifier*
High Technology Letters, Vol.6, No.3，-0001，（）：
A new approach of all optical wavelength converter based on four wave mixing (FWM)in a senlicon- ductor optical amplifier (SOA) with the conjugate wave reflected hv a fiber Bragg grating (FBG) and then amplified by the SOA is reposed. By adjusting the pump power, the conversion efficiency could be im-proved 7-10dB with signal-to-background-noise-ratio (SBR) deteriorated 1-2dB, compared with tradi- tional single pump four wave mixing.
