ABSTRACT:
A semiconductor laser device which operates stably at high power in the lowest order lateral mode is disclosed. Stable operation in the lowest order lateral mode is achieved by coupling the laser to a particular resonant mode of a Fabry-Perot resonator oriented perpendicular to the laser. Coupling between the laser and the resonator is illustratively achieved through use of an optical integrated circuit comprising two grating structures oriented orthogonally to each other.
