Optical switch, refers to the application of linear optical properties, so that the optical path in the transmission interruption or continue, in order to achieve the signal on or off. The simplest example is the interruption of light transmission with opaque separators. In MEMS, microdisplacement or angular rotation of a mirror is used to change the optical path of the reflected light, interrupting the transmission of light. In optical communications, Bragg gratings and the like can be used to reflect the light of the corresponding wavelength transmitted in the optical fiber back. The application of optical switch helps to realize all-optical network. In the future of light computer, will also be its basic unit.
