We propose and experimentally demonstrate mutual optical format conversion between signals characterized as 10-Gb/s nonreturn-to-zero on-of-keying(NRZ-OOK)and NRZ binary phase-shift keying(BPSK)types.The conversion is based on stimulated Brillouin scattering(SBS)in a single-mode optical fber.An OOK signal is converted into a BPSK signal through optical carrier absorption,for which a SBS loss of30 MHz is used in long-haul transmission.The converted BPSK signal is reverted to an OOK signal with a corresponding SBS gain of 30 MHz for direct detection.The proposed OOK-to-BPSK and BPSK-to-OOK format conversions can be implemented in transmitter and receiver nodes by using a laser source as the Brillouin pump.
