Abstract
A photonic integrated circuit (PIC) can include a quantum dot comb laser comprising a plurality of channels and a waveguide receiving laser output from the plurality of channels of the quantum dot comb laser. The PIC can further include a plurality of optical filters each coupled to the waveguide and outputting resonant optical output to a plurality of optical combiners. Each optical combiner couples the resonant optical output from a corresponding pair of optical filters to output a heterodyned optical signal.
