    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.

    摘要: A non-linear optical material comprising crystal grains of an oxide having a corundum type crystal structure, and amorphous portions in the surroundings of the crystal grains, in a thin film, is disclosed. The non-linear optical thin film has such a property that its refractive index varies largely when energy is applied thereto. Since the material shows little loss of light transmitted therethrough, it is possible, by use of the material, to provide a non-linear optical device for efficiently changing over the emission path of a light signal or turning-ON/OFF the light signal.
