Pulsed pump wavelength exchange for high speed signal de-multiplexing.
We report the first experimental demonstration of pulsed pump wavelength exchange in a highly nonlinear dispersion-shifted fiber for all-optical time de-multiplexing of 80 Gb/s return-to-zero (RZ) signals. Orthogonal pulsed pump and continuous wave (cw) pump are used in the fiber-based wavelength exchange for ultra-fast power switching. Error-free operation was achieved for the proposed all-optical 1:8 de-multiplexer over all time de-multiplexed 10 Gb/s RZ signals with <or=2.1 dB power penalty at 10(-9) bit-error rate. The experimental results show that a wide-band phase-matching is feasible for fiber-based nonlinear parametric processes.
