    摘要： Semi-integrated external cavity diode laser (ECDL) (300A) designs including integrated structures (302A) comprising a gain section (400), phase control section (402), and optional modulator section (404). Each integrated structure includes a waveguide (406) that passes through each of the sections. A mirror (408) is defined in the structure to define one end of a laser cavity. A reflective element (314) is disposed generally opposite a rear facet (410) of the gain section (400), forming an external cavity therebetween. A tunable filter (310) is disposed in the external cavity to effectuate tuning of the laser. During operation, a modulated drive signal (332) is provided to the phase control section (402). This modulates an optical path length of the laser cavity, which produces an intensity (amplitude) modulation in the laser output. A detector is employed to produce a feedback signal indicative of the intensity modulation that is used for tuning the laser in accordance with a wavelength locking servo loop. Upon passing through the modulator section (404), an optical signal is modulated with data (722).

    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.
