Abstract:
An optical switch comprising:a first input end for receiving a first ray; a second input end for receiving a second ray; a first output end; a second output end; a reflective device for receiving the first and second rays, wherein the reflective device further comprises: a flat glass having at least one optical plane; and a reflective element provided on the optical plane, wherein the reflective element is coated or attached on the optical plane and the reflective device includes a mirror disposed in parallel with the reflective element; and a switching device for changing a relative position between the reflective device and the first and second rays, wherein when the reflective device is moved away from the first and second input ends, the first ray and the second ray are output from the first output end and the second output end, respectively, and when the reflective device is moved close to the first and second input ends, the first ray and the second ray are output from the second output end and the first output end, respectively.
