Abstract:
1. A semiconductor optical emitting device comprising: an at least partially transparent substrate comprising a first surface and a second surface; an active semiconductor structure comprising a first surface, a second surface and at least one sidewall, the first surface of the active semiconductor structure facing the second surface of the substrate; a dielectric layer surrounding at least a portion of the at least one sidewall of the active semiconductor structure; and a metal layer surrounding at least an outer portion of the dielectric layer; wherein the at least one sidewall of the active semiconductor structure is tapered; wherein a first portion of the at least one sidewall of the active semiconductor structure has a different tapering than a second portion of the at least one sidewall of the active semiconductor structure; and wherein the active semiconductor structure comprises an active region proximate the second surface of the active semiconductor structure, the first portion of the at least one sidewall of the active semiconductor structure extending from the active region to the second surface of the active semiconductor structure.
