Integrated fiber optic coupler for vhsic/vlsi interconnects

Abstract From the Canadian patent

Abstract of the Disclosure, An integrated fiber optic coupler useful for the optical transmission of data from a light source to a detector located on a semiconductor chip which comprises a semiconductor wafer with a cavity etched into a surface, a device within the cavity for converting light into an electrical signal an, electroconductive metal deposited on the surface of the semiconductor wafer around the opening of the cavity forming an electrical connection between the device for converting light into an electrical signal and circuitry etched into the wafer and an optical fiber inserted into the cavity and affixed to the semiconductor wafer.
