Abstract

We demonstrate a method to use phase-modulated pumps for multicasting of return-to-zero differential phase-shift keying (RZ-DPSK) signals. The method uses phase modulation of the input signal along with the co-phase- modulated pumps prior to wavelength conversion. Nine copies of a 50 Gbit / s RZ-DPSK data signal are generated via four-wave mixing with an average conversion efficiency of 0 dB . An average receiver sensitivity penalty of 1.9 dB is observed at a bit-error rate of 10 9 with a worst case of 2.3 dB . The effects of synchronization errors and phase-modulation frequencies up to 5 GHz are investigated.
