The information revolution, which started in the 1960’s, has had a huge impact on society worldwide, although it now seems to be gradually slowing down. Semiconductor technology, one of the most important areas in the formation revolution, seems to be near saturation. Much discussion has been held regarding what will follow the 1 Gbit memory chip. Another important area is optical communications. It has succeeded in sending a lot of information at very high speed over very long distances, but this, too, seems to be close to its limit.
