Neural networks perform communication switching tasks. British researchers have successfully used neural networks to identify optimal paths for data routing. By Sunny Bains. Liquid crystals make fine optical switches. David Appel reports, Industry Focus .
Optical polymers achieve both optical and thermal stability.
BFGoodrich and 3M are developing devices that use the technology, which is based on polynorbornene polymers. David Appell reports, Industry Focus . New photorefractive polymers fastest yet. The polymer composites have a response time as low as 4 ms, which is well into the video response range. David Appell reports, Industry Focus .
