Patent 8257990 was granted and assigned to Intel on September, 2012 by the United States Patent and Trademark Office.
A silicon vertical cavity laser with in-plane coupling comprises wafer bonding an active III-V semiconductor material above a grating coupler made on a silicon-on-insulator (SOI) wafer. This bonding does not require any alignment, since all silicon processing can be done before bonding, and all III-V processing can be done after bonding. The grating coupler acts to couple the vertically emitted light from the hybrid vertical cavity into a silicon waveguide formed on an SOI wafer.
