Abstract:
1. A light-emitting device with a current blocking structure comprising: a substrate; an epitaxial structure positioned on said substrate, said epitaxial structure having a bottom cladding layer and an upper cladding layer, said epitaxial structure having a light-emitting layer positioned between said bottom cladding layer and said upper cladding layer, said epitaxial structure having a window layer positioned on said upper cladding layer; an ohmic contact electrode positioned on said epitaxial structure; and a current blocking structure positioned inside said epitaxial structure, said current blocking structure extending from a region below said ohmic contact electrode to at least said light-emitting layer, said current blocking structure having an area that is smaller than an area of said ohmic contact electrode, said current blocking structure extending to said bottom cladding layer.
