Optical computing is the use of photons rather than electrons for computing architecture. Optical analogues for microelectronic devices can be used to generate, modulate, and process streams of light and perform computational tasks. Photon-based computing overcomes drawbacks of electron-based computing including quantum tunneling, which limits the minimum size of electron transistors, and electron drift velocity, which is much slower than the speed of light. Optical computing chips can be used in various sensing and imaging capabilities, especially those that require multivariate analysis or neural network applications.
