Abstract

A surface emitting photonic device including a substrate; and a waveguide structure on the substrate. The waveguide structure includes an active region along its longitudinal axis and the active region is for generating light. The waveguide structure also has a trench formed therein transverse to the active region and defining a first wall forming an angled facet at one end of the active region, the first wall having a normal that is at a non-parallel angle relative to the longitudinal axis of the waveguide structure. The trench also defines a second wall located opposite the first wall.
