Thanks for pointing out Lucent's product. Is it based on MEMS as referred to in this article?nytimes.com Bell Laboratories, the research arm of Lucent Technologies in Murray Hill, N.J., is using microelectricalmechanical systems, known as MEMS. Its optical switches use silicon chips tiled with micromirrors, each one small enough to fit on the head of a pin. When a voltage is applied to the chip, the mirrors are pulled up or down in response. The result is a tilting motion that can redirect light in three dimensions. "You can steer the light from any input fiber to any output fiber," said David Bishop, head of MEMS research at Bell Labs. The device carrying the switches, Dr. Bishop added, could be the size of a grapefruit. If so, the size differential is obvious compared to the product claims of Nanovation. One certainly has to keep in mind that there must be many others out there working on this same problem. A list, probably incomplete of possible sources of competition: Optical Switch Manufacturers Allied Signal, AMP, ATT, Chorum, Corning, Dicon Fiber Optics, JDSU, Lighthouse Digital Systems, Lightwave Microsystems, Lucent, Nortel, Optical Micro-Machines, Optical Switch Corp., Photonic Integration Research Inc. (PIRI), Spectra Switch, Texas Instruments, Xnos Inc., Alcatel, Bookham Technologies, Kymata, Asahi, FDK Corp., Fujukura, Furukawa Electric, Hitachi, NEL, NTT Electronics From: strategies-u.com Nanovation claims proprietary technology licensed from Northwestern. I can find five patents in the name of Seng-Tiong Ho but do not have the technical background that would enable me to tell if these would be the basis for an all optical switch. patents.ibm.com Was anybody reading this at the National Fiber Optic Engineers Conference in September where Nanovation supposedly demo'd its technology?
