Abstract:
1. A telecommunications system, comprising: a multi-frequency continuous wave light source configured to emit a continuous wave having a plurality of frequencies, wherein said plurality of frequencies are generated by proper four-wave mixing in a nonlinear medium, said multi-frequency continuous light source including one laser diode coupled to an optical multiplexer; a demultiplexer, coupled to said multi-frequency continuous wave light source and configured to demultiplex said continuous wave so as to provide a plurality of lightwaves; a plurality of modulators, coupled to said demultiplexer, configured to modulate said plurality of lightwaves so as to provide a plurality of optical signals; a multiplexer, coupled to said plurality of modulators and configured to multiplex said plurality of optical signals so as to provide a wavelength division multiplexed optical signal; an optical transmission line, coupled to said multiplexer; a demultiplexer, coupled to said optical transmission line and configured to demultiplex output signals from said optical transmission line into a plurality of optical signals; and an optical receiver, coupled to said optical transmission line, configured to receive said plurality of optical signals.
