摘要：

We propose an all-optical modulation format conversion scheme from non- return-to-zero on-off-keying (NRZ-OOK) to return-to-zero (RZ) multiple- level phase-shift-keying (PSK) based on nonlinearity in optical fiber. The proposed conversion scheme is numerically investigated and experimentally demonstrated. We experimentally demonstrate error-free operation of NRZ-OOK/RZ-binary PSK conversion at 10.7 Gb/s. The operation of the NRZ-OOK/RZ-quadrature PSK conversion is shown by eye opening after balanced receiving at a symbol rate of 10.7 Gsymbol/s. In addition, we demonstrate the feasibility of the modulation format conversion from NRZ-OOK to RZ-8- levels PSK by numerical simulation. (C) 2007 Optical Society of America
