Abstract:
A method for generating optical communication signals in a communication network includes (1) generating at least a first optical tone and a second optical tone using a quantum dot (QD) coherent comb laser (CCL), the first and second optical tones having different respective wavelengths, (2) modulating the first optical tone according to a first modulation signal to generate a first communication signal, and (3) modulating the second optical tone according to a second modulation signal to generate a second communication signal.
