Abstract
A semiconductor substrate includes an active waveguide to guide optical signals to be amplified occupying signal channels within a gain band of the waveguide. A stabilizer system comprises two Bragg reflectors tuned to a resonant wavelength in the gain band but outside the signal channels. It includes a gain segment in a resonant cavity. Two rejector Bragg reflectors sandwiching the resonant cavity between them are tuned to the resonant wavelength. Applications include telecommunication systems.
