摘　　要：We present an all-optical nonreturn-to-zero/return-to-zero （NRZ/RZ） to carrier-suppressed return-to-zero （CSRZ） format conversion scheme for differential phase-shift keying （DPSK） signals. The conversion is based on nonlinear polarization rotation of a semiconductor optical amplifier （SOA）. The 4-channel NRZ-DPSK or RZ-DPSK signals at 10 Gb/s are simultaneously converted to the corresponding CSRZ-DPSK signals, with -0.8 and 1.4 dB average power penalties, respectively. Additionally, high quality format conversion performances are shown with the optical spectra and eye diagrams.We present an all-optical nonreturn-to-zero/return-to-zero （NRZ/RZ） to carrier-suppressed return-to-zero （CSRZ） format conversion scheme for differential phase-shift keying （DPSK） signals.
