    • An optical path switching method according to the present invention comprises converging and irradiating, on a light absorption layer film provided in a thermal lens forming element (1, 2, 3) including at least the light absorption layer film, each of a control light (121, 122, 123) having a wavelength selected from a wavelength band which is absorbed by the light absorption layer film and a signal light (110, 111, 112) having a wavelength selected from a wavelength band which is not absorbed by the light absorption layer film. Arrangement of the light absorption layer film is adjusted such that at least the control light focuses within the light absorption layer film. A thermal lens is reversibly formed according to a distribution of refraction index created by a temperature increase generated in and around an area of the light absorption layer film in which the control light is absorbed, such that, according to whether or not the control light is irradiated, the converged signal light is output either as is in its converged form or after its spread angle is changed and a mirror (61, 62, 63) including a hole and reflecting means, the signal light output from the thermal lens forming element is either passed through the hole or reflected by the reflecting means to change the optical path.

    • The present invention provides a method of controlling light and an apparatus of controlling light capable of extracting sufficiently large and speedy optical responses from the photoresponsive photoelement with a high reproducibility, wherein the control light is emitted from the light source 1, and the signal light from the light source 2. The control light and signal light are converged by the converging lens 7, and illuminated to the film photoelement 8 filled in with the photoresponsive composition. Via the collimate lens 9 and the band-pass filter 20, only the signal light is detected with the photodetector 22. By turning the control light on and off, the transmittance and/or refractive index of the signal light are reversibly increased or decreased, realizing the modulation of photointencity. By setting the numerical aperture of the collimate lens at the value essentially smaller than the numerical aperture of the collimate lens, sufficiently large and speedy optical responses can be extracted from the photoelement comprised of photoresponsive composition containing dye.
