Abstract

The invention relates to a substrate for an optical device and an optical device package having the same. The invention especially relates to a substrate for an optical device, wherein the substrate is applied to the inclined surface of a cavity of an optical element to reduce the roughness and is used to minimize the optical loss; and an optical device package having the same.

Description

technical field [0001] The present invention relates to a substrate for an optical device and an optical device package provided therewith, and more particularly, to a substrate for an optical device that minimizes light loss by reducing the surface roughness of an inclined surface of the substrate for an optical device The substrate and the optical device package with it. Background technique [0002] An optical device package refers to a device that mounts an optical device to generate light. [0003] In this case, an optical device refers to an element that receives an electrical signal to generate light. [0004] The light emitting diode (Light Emitting Diode, LED) in this optical device is not only more efficient than the previous optical device, but also can generate high-brightness light, so it is widely used in the display field. [0005] An optical device package can be produced by disposing an optical device or the like on a substrate for an optical device. [0...
