I haven't kept up with this stuff but would love to hear from folks who do. IBM has combined light and electronic switching circuitry on one chip in a manner that hasn't been done before that enables much higher speed and lower power consumption.

"Dave, I wouldn't do that"


At Semicon Japan in Chiba, Japan, IBM (Armonk, N.Y.) heralded silicon nanophotonics as the enabler for future exascale processors that can execute a million trillion operations per second (1,000-times faster than today's petascale supercomputers).

For nearly a decade, IBM, Hewlett-Packard Co., Intel Corp., Freescale Semiconductor Inc., NEC Electronics Corp., Samsung Electronics Co. Ltd., IMEC and dozens of their partners—from Avago Technologies Ltd. to Luxtera Inc.—have promised silicon photonics as the inevitable future of CMOS. By integrating electrical-to-optical and optical-to-electrical transceivers onto traditional CMOS chips, silicon photonics promises to break the bottleneck now holding back development of exascale computing platforms. IBM now claims to have solved this problem with its CISN technology which is currently being licensing to partners, and which will begin to appear in commercial transceivers starting in 2011
