All-optical switches were also drawing lots of interest. Most switches on the market today require that optical signals be converted to electricity before they can be redirected to another fiber. Optical switches eliminate these conversions. While still not a panacea, these somewhat futuristic boxes are getting closer to commercial deployment. Various methods for steering light signals from one fiber to the next were demonstrated. The most common is something called micro electro mechanical systems (MEMS), in which a large number of tiny, tilting mirrors are fabricated on a semiconductor substrate. Though it sounds strange, MEMS have been widely used in automotive sensors and other applications. Companies demonstrating MEMS components included Analog Devices (NYSE: ADI - news), JDS Uniphase, and Corning, while Lucent, Nortel, and Calient are building complete systems using the technology. Other promising optical switching technologies included holograms (Trellis Photonics), and bubbles (Agilent (NYSE: A - news)).
