| titleOfInvention | Optical path switching device and optical path switching method |
| abstract | In the optical path switching method according to the present invention, the control light 121 having a wavelength selected from the wavelength band absorbed by the light absorption layer film is absorbed into the light absorption layer film of the thermal lens forming elements 1, 2, 3 including at least the light absorption layer film. And converging and irradiating signal lights 110, 111, and 112 having wavelengths selected from wavelength bands not absorbed by the light absorption layer film. The arrangement of the light absorption layer film is adjusted so that at least the control light is focused in the light absorption layer film. Based on the distribution of refractive indexes caused by the temperature rise occurring in the region where the light absorption layer film absorbs the control light and its surrounding area, the thermal lens is reversibly formed, and according to whether or not the control light is irradiated, the converged signal light Is emitted after converging or after changing the opening angle thereof, and the signal light emitted from the thermal lens forming element is passed through the hole by using the mirrors 61, 62, and 63 having holes and reflecting means. Alternatively, the optical path is changed by reflecting by the reflecting means. n n Optical path switching device, optical path switching method, thermal lens forming element, refractive index distribution. |
