Abstract:
1. A surface emitting photonic device comprising: a substrate; and a waveguide structure on the substrate, said waveguide structure including an active region along a longitudinal axis of the waveguide structure, said active region for generating light, wherein the waveguide structure has a trench formed therein transverse to and intersecting the active region in the waveguide structure, a first side of the trench forming an angled facet at one location along the waveguide structure and a second side of the trench forming a wall at a second location along the waveguide structure, said angled facet having a normal that is at a non-parallel angle relative to the longitudinal axis of the waveguide structure, and wherein the active region of the waveguide structure is interrupted by the trench between the first and second sides of the trench.
