Our approach exploits four-wave mixing by the instantaneous nonlinear response of chalcogenide.Keywords: Fibers; Four wave mixing; Optical fibers; Optical materials; Optical waveguides; Planar waveguides; Time division multiplexing; Waveguides; 10Gbit/s; Non-linear responses; Otdm signals; Demultiplexing200810.1109/OECCACOFT.2008.46103182015-12-09
