Gallium and nitrogen containing trilateral configuration for optical devices

摘要

Techniques for manufacturing optical devices, such as light emitting diodes (LEDs) using a separation process of thick gallium and nitrogen containing substrate members, are described.

主权项

1. An optical device comprising a substrate structure, wherein the substrate structure comprises:
a first triangular facet characterized by a first planar surface; a second triangular facet characterized by a second planar surface; and three sidewalls connecting the first triangular facet and the second triangular facet, wherein,
each of the three sidewalls comprises a first portion coupled to the first triangular facet and a second portion coupled to the first portion and to the second triangular facet;each of the first portions is oriented orthogonal to the first triangular facet; andeach of the second portions is oriented non-orthogonal to the first triangular facet.
