Patent ID: 8278668

Claim:
A luminous device, comprising: a luminous structure having a light-emitting first surface, a second surface, at least one side surface inclined at an angle compared to the second surface, an active layer having a first surface and a second surface, a first cladding layer abutting the first surface of the active layer and providing the first surface of the luminous structure, a second cladding layer abutting a second surface of the active layer and providing the second surface of the luminous structure, and at least one groove separating at least the second cladding layer and the active layer while provide at least a continuous portion of the first cladding layer, wherein one portion of the groove defines a major portion of the luminous structure and another portion of the groove defines a minor portion of the luminous structure; an insulation layer on at least a portion of the at least one side surface and the second surface of the luminous structure, wherein the insulating layer includes a recess exposing at least a portion of the second cladding layer; a patterned first electrode layer in the recess and on at least a portion of the insulation layer, wherein the first electrode layer is discontinuous in the groove region; an insulated through via contact extending from the first electrode layer to the first cladding layer of the minor portion of the luminous structure; and a conductive substrate attached to the first electrode, wherein the conductive substrate comprises a patterned conductive intermediate layer having a first portion for attachment to the surface of the first electrode layer corresponding to the recess, and a second portion for electrical communication with the through via contact.
