| Abstract: | Based on the rate equation of semiconductor optical amplifier (SOA) and the transmission equation of the probe and pump light in SOA, a small signal model for the relation of the output extinction ratio with conversion rate in cross gain modulation wavelength converter has been developed and calculated with various pump power. The analysis on the result obtained reveals the significant influence of conversion rate on output extinction ratio. |
