An optical transistor, also known as an optical switch or a 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 … WebCircuit switching is defined as The switching technique is a connection-oriented network that is divided into pieces and has a dedicated path established between the sender and receiver providing a guaranteed data rate.
