An optical transistor, also known as photonic transistor, optical switch or light valve, is a device that switches or amplifies optical signals. Light occurring on an optical transistor''s input changes the intensity of light emitted from the transistor''s output while output power is supplied by an additional optical source. Since the input signal intensity may be weaker than that of the source, an optical transistor amplifies the optical signal. The device is the optical analog of the electronic transistor that forms the basis of moder
