An integrated circuit with a number of optical fibers that are formed in high aspect ratio holes. The high aspect ratio holes extend through a semiconductor wafer. The optical fibers include a cladding layer and a core formed in the high aspect ratio hole. These optical fibers are used to transmit signals...http://www.google.de/patents/US20040156578?utm_source=gb-gplus-sharePatent US20040156578 - Integrated circuits using optical fiber interconnects formed through a semiconductor wafer
