| Abstract(in English) | We investigated the change of the operation characteristics of an optical regenerator using SOA gain-saturation and polarity inverted XGM signal by the timing offset between signal and XGM signal. Nonlinearity in input/output characteristics by gain saturation can be achieved at both '1' and '0' level of input signal due to continuous total input light power of original signal and XGM signal. It is expected that smaller change of total light power than the conventional gain saturation could cause the reduction of frequency chirping and that the extinction ratio could be maintained by using the amplified input signal as a regenerated one. Moreover, the decrease of power for red-chirp component was realized by the flter detuning method, and the of shift red chirp component into low power side was observed by the input timing offset between signal light and XGM signal light for a SOA. By thease methods, the improvement of received sensitivity and 50km transmission with BER of less than 10^<-12> for the degraded signal with BER of more than 10^<-9> was achieved. |
