Abstract:
An optical switch using tilt mirrors comprising;a collimator array formed with an input section arranged with a plurality of input collimators and an output section arranged with a plurality of output collimators, said input section and said output section being aligned within the same plane; a tilt mirror array formed with an input section arranged with a plurality of input tilt mirrors each of which has a reflection surface with an angle thereof being controllable and an output section arranged with a plurality of output tilt mirrors each of which has a reflection surface with an angle thereof being controllable, said input section and said output section being aligned within the same plane; and a shift type turn-back mirror for shifting an optical path of incident light in a predetermined direction and turning back and outputting this light, wherein the light output from the respective input collimators of said collimator array, is reflected by the corresponding input tilt mirrors of said tilt mirror array so that the optical path is changed, and is then sent to said shift type turn-back mirror, and the light which has been shifted and turned back by said shift type turn-back mirror is reflected by the corresponding output tilt mirrors of said tilt mirror array and then respectively output from the respective output collimators of said collimator array.
