Claim:
1. An optical transmitter, comprising: a first optical light source configured to generate a first optical frequency comb output having multiple channels whose frequencies are locked together; a second optical light source configured to generate a second optical frequency comb output having multiple channels whose frequencies are locked together; an optical switch, including an optical output; a detection unit configured to: a tone separator configured to wavelength division demultiplex the multiple channels of the second optical frequency comb output into multiple outputs, with each channel of the multiple channels being output via a different output of the multiple outputs; a plurality of optical modulators, comprising one of the plurality of optical modulators for each channel of the multiple channels, and configured to modulate light of the multiple channels of the second optical frequency comb output based on data to be transmitted; and a tone combiner configured to wavelength division multiplex the modulated light of the multiple channels into a single output.
