In the information industry there has always been a high demand for photonic/optical solutions, however these products are still not widely available today. The important technology of photonic switching through asynchronous transfer mode (ATM) is crucial to the development of cost-efficient high speed optical communication systems and broadband integrated service digital networks (B-ISDN). ATM is a switching method which separates the information from sources (audio, video and data channels) into fixed size cells, using headers to distinguish between channels. These cells can then be transmitted and interchanged within the same network. A major advantage of employing photonic switching is to avoid the electronic system's bottleneck effect due to optical-electrical-optical conversions to and from optical fibers, and to safeguard from electromagnetic influence. As a consequent, this technology increases both the transmission capacity and switching speed, thus reducing the cost of network switching.
