Abstract:
An optical switch system, for switching over plural input lights and plural output lights corresponding thereto through spatial optical connection therebetween, comprising:a first reflection mirror to be directed with an input light and being controllable in position thereof; a second reflection mirror disposed opposite to said first reflection mirror, for reflecting the light reflected on said first reflection mirror, so as to outputted it therefrom; means for controlling positions of said first reflection mirror and said second reflection mirror, respectively; and means for adjusting the position of at least one of said first and second mirrors, which are controlled by said controlling means by means of a reference light being substantially different from said input light in wavelength thereof; wherein said position adjusting means adjusts the position of at least the one of said first and second mirrors, so that the input light, reflecting upon said first reflection mirror and propagating onto said second reflection mirror, comes to the maximum in the optical intensity thereof.
