Abstract
Optical circuit architectures utilizing primary laser light sources and at least one auxiliary laser light source. The primary lasers may be fixed-wavelength lasers and/or comb lasers, and the auxiliary lasers may be fixed-wavelength lasers, tunable-wavelength lasers, and/or comb lasers. In some cases optical switches are utilized along the optical paths in various configurations between the laser inputs and output terminals of the optical paths or between the laser inputs and a transform network.
