All-Optical Wavelength Conversion for Orthogonal Frequency Division Multiplexing Optical Signal
We experimentally demonstrate three schemes of pumping including single pump,orthogonal-dual-pump and copolarized-dual-pump based on four-wave mixing (FWM) in semiconductor optical amplifier (SOA) for the wavelength conversion of optical amplifier (OFDM) signals. In experiment,the signal continuous-wave (CW) lightwave is modulated directly by 2.5 Gb/s OFDM. The modulated signal lightwave and pump light are coupled and then amplified before they are injected into the SOA for wavelength conversion. Experimental results show that the newly converted wavelength signals carry the original OFDM signals. The bit error rate (BER) curves and received constellations are also measured by experiment,the experimental results show that the copolarized-dual-pump configuration has the smallest system power penalty,which agree well with the theoretical analyses.
