We propose and experimentally demonstrate a compact all-optical DPSK wavelength multicasting scheme using dual-pump FWM in a Bi-HNLF with only 2-m long. Less than 0.6-dB power penalty is obtained for the converted signals.
We have demonstrated an all-optical wavelength conversion and multicasting for a 10 Gb/s NRZ system with 100GHz channel spacing by using a single-stage two-pump fiber optical parametric amplifier (OPA) with the conversion gain of at least 15dB.
