Abstract: Unidirectionality of lasers is enhanced by forming one or more etched gaps in the laser cavity. The gaps may be provided in any segment of a laser, such as any leg of a ring laser, or in one leg of a V-shaped laser. A Brewster angle facet at the distal end of a photonic device coupled to the laser reduces back-reflection into the laser cavity. A distributed Bragg reflector is used at the output of a laser to enhance the side-mode suppression ratio of the laser.
