Integrated optical transceiver chip

Abstract

A transceiver is described which utilizes D-shaped optical fiber technology and advanced flip chip mounting techniques for manufacturing an integrated transceiver chip for use in electronic microcircuit applications. A single D-shaped optical fiber is used for bi-directional signal transmission, with coupling gratings superimposed on the flat surface of the fiber for coupling light into and out of the optical fiber. A light source and optical detector, aligned with the respective coupling grating for optical communication with the fiber, are flip mounted on the substrate which supports the fiber. Finally, the light source and optical detector are electrically connected with associated electronic circuitry also mounted or fabricated on the substrate.
