Abstract
Official abstract text for this publication.
An optoelectronic chip including a coupler region, and a method of manufacturing the same, include a substrate; a coupler region formed of a material having a refractive index lower than the substrate and surrounded by the substrate. The coupler region includes a total reflection surface that totally reflects light incident through a surface of the substrate into the substrate or emits light guided in the substrate through the surface of the substrate.
First claim
Opening claim text (preview).
What is claimed is: 1. An optoelectronic chip, comprising: a substrate including a first layer, a second layer and a third layer, sequentially stacked, the first layer having a first surface and a second surface, the first surface being an interface with outside, and the second surface being an interface with the second layer; and a coupler region formed of a material having a refractive index lower than a refractive index of the first layer and surrounded by the first la…
