Abstract :
Summary form only given. We have demonstrated wavelength conversion of 60 QPSK channels from 1555 nm to 1520 nm via cross-gain modulation in a semiconductor optical amplifier. There is a tradeoff between conversion efficiency and distortion, as evidenced by BER floors from nonlinearities when higher input signal powers were used to improve the output optical modulation depth.
