The architecture used a two-pump broadband fiber-optic parametric amplifier for multicasting, and a single 40-GHz optical parametric sampling gate in a highly nonlinear fiber. Using this architecture, we demonstrate parallel demultiplexing of four 320-Gb/s tributary channels. All demultiplexed channels were measured with a -factor better than 15 dB.Four-photon mixingmulticastingoptical fiber communicationsoptical gate demultiplexingoptical parametric amplifieroptical time-division multiplexing (OTDM)parametric processsamplingtext::journal::journal article::research article
