Abstract
A semiconductor optical emitting device comprises an at least partially transparent substrate, an active semiconductor structure, a dielectric layer and a metal layer. The substrate comprises a first surface, a second surface and at least one sidewall. The active semiconductor structure comprises 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. The dielectric layer surrounds at least a portion of the at least one sidewall of the active semiconductor structure. The metal layer surrounds at least a portion of the dielectric layer. The at least one sidewall of the active semiconductor structure is tapered and 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.
