【Abstract】 All-optical regeneration of high repetition picosecond pulse based on self-phase modulation(SPM)in a highly nonlinear photonic crystal fiber(PCF)is proposed.Transmission characteristics of the regenerator and filter parameters on regenerator performance are investigated.Furthermore,all-optical regeneration using an 80-m-long nonlinear photonic crystal fiber is demonstrated experimentally.By adjusting the input power into the fiber and the parameters of the tunable filter,optical regeneration for high bit rate signals is achieved.The experiment results agree well with the theoretical results.更多还原
