Latest Patents

Gong-Cheng Lin holds a patent for a "Method for improving a high-speed edge-coupled photodetector." This invention features an edge-coupled photodetector, especially a compound semiconductor edge-coupled photodetector, which incorporates a light funnel integrated right in front of the coupling aperture. This design aims to enhance the optical coupling efficiency. The light funnel can be formed using either a wet etched, crystallographically defined semiconductor slope or a dry etched, resist-profile-defined semiconductor slope covered by planarized dielectrics. The funnel internals can be partially or fully metallized for total mirror reflection. The lightwave entering the funnel and propagating along the optical axis converges through mirror reflection or total internal reflection. This invention allows the edge-coupled photodetector to achieve both high operation speed and high quantum efficiency with enlarged alignment tolerance.
