Optical computing is the use of photons in computation.

▪️Photons, effectively massless and incredibly fast, are generated using diodes or lasers. The photons take the place of electrons in more traditional computers and are used to represent the flow of data. Lacking the size limitation of electrons, photon based transistors can be incredibly small which increases potential computing power.

▪️ The need for Optical Computer emerged from the fact that conventional computers are limited by the slow time response of electronic circuits and also the building up of heat damages the electronic

components.

▪️The working principle of Optical Computer is similar to the conventional computer except with some portions that performs functional operations in Optical mode. Photons are generated by LED’s, lasers and a variety of other devices.

▪️ They can be used for encoding the data similar to electrons
