An optical computer is a computer that uses light instead of electricity to manipulate store and transmit data. Photons have fundamentally different physical properties than electrons and researchers have attempted to make use of these properties mostly using the basic principles of optics to produce computers with performance and/or capabilities greater than those of electronic computers. Optical computer technology is still in the early stages: functional optical computers have been built in the laboratory but none have progressed past the prototype stage.
Most research projects focus on replacing current computer components with optical equivalents resulting in an optical digital computer system processing binary data. This approach appears to offer the best short-term prospects for commercial optical computing since optical components could be integrated into traditional computers to produce an optical/electronic hybrid. Other research projects take a non-traditional approach attempting to develop entirely new methods of computing that are not physically possible with electronics.
