Abstract
A self-calibrating integrated photonic circuit and a method of controlling the same. In one embodiment, the circuit includes: (1) a substrate, (2) a laser located on the substrate and configured to produce source light at an output frequency, (3) a laser alignment sensor located on the substrate and including: (3) a reference optical resonator configured to receive the source light, have a null proximate a predetermined center frequency and provide output light as a function of a relationship between the output frequency and the center frequency and (3) a photodetector configured to provide an electrical signal of a magnitude that is based on the output light and (4) a calibration controller located on the substrate, coupled to the photodetector and configured to adjust the output frequency based on the magnitude.
