| 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 $\sim$0?dB. An average receiver sensitivity penalty of $\sim$1.9?dB is observed at a bit-error rate of 10{\textminus}9 with a worst case of 2.3?dB. The effects of synchronization errors and phase-modulation frequencies up to 5?GHz are investigated. |
