Performance Analysis for the Variations of Input Intensity and Converted Wavelength in Wavelength Converters by XGM in SOA's
초록
We demonstrate wavelength conversion of 2.5 Gb/s optical signals by cross-gain modulation (XGM) in a semiconductor optical amplifier (SOA). We investigate the effect of input pump and probe powers on the extinction ratio and power penalty to be a measure of performance in wavelength converters. As a result, we show that the best bit error rate (BER) performance can be obtained when the probe power is kept 3 dB weaker than the pump power. And we investigate the effect of wavelength detuning on performance in wavelength converters.
