英文摘要	An optical source includes a semiconductor optical amplifier that provides an optical signal, and a photonic chip with first and second ring resonators that operate as Vernier rings. When the optical source is operated below a lasing threshold, one or more thermal-tuning mechanisms, which may be thermally coupled to the first ring resonator and/or the second ring resonator, may be adjusted to align resonances of the first ring resonator and the second ring resonator based on measured optical power on a shared optical waveguide that is optically coupled to the first and second ring resonators. Then, when the optical source is operated above the lasing threshold, a common thermal-tuning mechanism may be adjusted to lock the aligned resonances with an optical cavity mode of the optical source based on a measured optical power on an optical waveguide that is optically coupled to the first ring resonator.
