    KYOTO, Japan — IBM researchers have integrated a 10-Gbps silicon photodetector using a 130-nm 1.5V CMOS process, opening the way to chip-to-chip and board-to-board optical interconnects. Eventually, optical photodetectors may be used for chip-level interconnects as well. By 2010, when processors exceed clock frequencies of 11.5 GHz, optical interconnects may be needed to avoid chip-to-chip and on-chip bottlenecks. In a presentation here Wednesday (June 11th) at the 2003 Symposium on VLSI Technology, Min Yang, a research staff member at the IBM Watson Research Center at Yorktown Heights, N.Y., described a monolithically integrated photodetector that achieves a much higher data detection...
