Optical Computers: A New Era of High Speed Computing Based On Photons

In the present era of science, technology and engineering computers have facilitated our life up to the great extent. The computation speed of computers have increased to astonish level. Research says speed of electron has attain their maximum speed and we reached at a stage that nothing could be further expected from electrons. According to Moore's Lawstates law in which the number of transistors on a computer chip doubles every eighteen months and speed will be increase with 2 time in every six months. We can easily see the fact about speed and number of transistor in today's computers. The Traditional transistors which are the building block of modern computers can no longer keep up, because too many transistor will slow down processor speeds and also transistors have physical size limits. Again metallic copper wires have their speed of transmission also resistance per unit length in the chip increased, causing more power usage and excess heating. An optical computer (also called a photonic computer) is a device that uses the photons in visible light or infrared (IR) beams, rather than electric current, to perform digital computations. They can perform operations 10 or more times faster than any conventional electronic computer. We can easily track electrons and also we can easily copy it but in optical computer exact location and speed can be calculated due to Heisenberg's Uncertainty Principle
