Abstract
A system and a method of manufacture for a semiconductor laser with a continuous waveguide ridge extending the length of the laser. The continuous waveguide ridge is positioned through the center of the optical components of the semiconductor laser. The optical components including the waveguide ridge may be distributed Bragg reflectors (DBRs), outcoupling gratings, and phase controllers. The illustrated embodiments include lateral-grating grating-stabilized edge-emitting lasers and lateral-grating grating-stabilized surface-emitting (GSE) lasers. Both loss-coupled and non-loss-coupled lateral-grating components are illustrated.
