As far as I know, TI still actively involved in area - chips now have about 1 million mirrors which can be switched between two different angles, effectively turning pixels on or off. Intensity is controlled by varying on-time. Don't remember switching time but must be well less than millisecond because used for video and cinema projectors. Best projectors use 3 chips(one per color) and are now about equal or better than typical 35-mm film in a Cineplex. Too expensive for most of home projection market, but used for some commercial video and computer projection. These devices do work and will probably be the basis for electronic cinemas in a couple of years. Content may be sent from central location to all theaters on demand, eliminating cost of prints. Uncompressed will require gigabits/sec - hopefully sent over fiber network with JDSU components. There are lots of TI papers on the Internet (they call it DLP - digital light processing) including a recent status report on their digital electronic cinema project. Micro mechanical systems are certainly feasible and are probably coming. Perhaps miniature quartz prisms that can select any of the individual wavelengths of a DWLM optical stream? There may also be approaches with no moving parts. I don't have expertise in the area of Photonics, but have had exposure in the motion picture and electronics industries.

Go back a few years in Scientific American and you'll find a nice article about them. Texas Inst. invented them years ago, and tried to commercialize them for projection TV's. Didn't work out. Too hard to manufacture. Of course, Lucent's will be slightly different, and their purpose requires far fewer mirrors than pixels on a TV. sciam.com
