Optics is the science of light and has a very long history. In the modern world of telecommunication and Information and Communication Technologies (ICT), the term "Photonics" is sometimes used for the application of optical technology, such as lasers and optical fiber, in electronics. In the past, high costs have prevented optical components from finding their way into computers. But as optical technology matures, prices drop and the limits of miniaturization appear to have been reached, the computer industry is re-evaluating the situation and incorporating optical alternatives into computer systems.
