    摘要: An optical switch, in which focal position of beams is adjusted to provide a high switching efficiency and a high stability in action without increasing a light source output of a control light, comprising a condensing means for making a signal light and a control light convergent and incident upon a nonlinear optical thin-film and wherein irradiation of the control light causes a change of the nonlinear optical thin-film in refractive index to thereby change the signal light into a transmitted light or a reflected light to take out the same as an output signal.
