Abstract
The disclosed embodiments relate to a system that locks a wavelength of a hybrid laser to a wavelength of a reference laser, wherein a lasing cavity of the hybrid laser includes a reflective gain medium (RGM) comprising an optical gain material coupled with an associated reflector, a phase tuner, a laser ring filter and a silicon mirror. During operation, while the hybrid laser is turned off, the system tunes a reference ring filter to the wavelength of the reference laser. Next, the system turns on the hybrid laser. The system then tunes the laser ring filter in the hybrid laser to the reference ring filter. Finally, the system adjusts the phase tuner in the hybrid laser to align a lasing cavity mode of the hybrid laser with the tuned laser ring filter.
