Abstract

Embodiments of the present disclosure are directed toward techniques and configurations for an optical coupler. In some embodiments, the device may include an optical waveguide to transmit light input from a light source. The optical waveguide may include a semiconductor layer, having a trench with one facet that comprises an edge formed under an approximately 45 degree angle and another facet formed substantially normal to the semiconductor layer. The edge may interface with another medium to form a mirror to receive inputted light and reflect received light substantially perpendicularly to propagate the received light. Other embodiments may be described and/or claimed.

Claims12

Dependent claims

An optical apparatus comprising:

an optical waveguide to transmit light input from a light source, wherein the optical waveguide includes a layer of first dielectric material and first and second portions, wherein the first portion is to receive the light from the light source, and the second portion is formed from a second dielectric material having a first end to receive the inputted light and a second end that comprises an edge formed under an approximately 45 degree angle, wherein the edge interfaces with the layer of first dielectric material to form a mirror to reflect the received light substantially perpendicularly to propagate the received light, a spacer coupled with the second portion to output the light reflected by the mirror, wherein the spacer comprises a third dielectric material with a first numerical aperture value that is lower than a second numerical aperture value of the second portion.

Dependencies are inferred from the claim text.
