Abstract: An optical switch includes plural pairs of ports and first lenses, each of the ports emitting light in a diffused manner or receiving light input thereto in a collected manner, and the first lenses respectively collimating light emitted from the ports; a second lens that collects the light collimated by the first lenses; and an inclinable mirror that reflects the light collected by the second lens at different angles toward the second lens. A position of a first lens is adjusted based on a first distance between a core of the second lens and a portion of the second lens through which light collimated by the first lens passes.

Abstract: When a solution sprayed by a spray nozzle portion reaches one surface portion of a substrate, a thin film forming material contained the solution decomposes thermally because the substrate is heated to a prescribed temperature, and a thin film is formed on the one surface portion of the substrate. An imaging section obtains a prescribed information on the thickness of a thin film to be formed on one surface portion of the substrate, and a main control section controls a valve section based on the prescribed information from the imaging section. Since, based on the prescribed information on the thickness of a thin film to be formed on one surface portion of the substrate, the main control section allows the spraying nozzle portion to spray the solution therefrom, a thin film of the desired thickness can be formed with high accuracy.

Abstract: A chromatic dispersion generating apparatus of the present invention comprises a VIPA plate capable of emitting an incident light to different directions according to wavelengths, a three-dimensional mirror reflecting the light of respective wavelengths emitted from the VIPA plate at a previously set position to return them to the VIPA plate, and a control section that controls a position of the three-dimensional mirror and the temperature of the VIPA plate.

Abstract: In a dispersion slope compensator of the invention, angular dispersion of a WDM light in which the angular dispersion is already performed in a first direction (Y-axis) with a VIPA plate is performed in a second direction (X?-axis) perpendicular to the first direction with a diffraction grating, and the WDM light is reflected from a three-dimensional mirror and returned to the VIPA plate side. At this point, the three-dimensional mirror is mounted on a rotating stage while placed on a linear-moving stage, which moves the three-dimensional mirror in parallel in the second direction. Thereby, the rotating stage can adjust an angle of a reflection plane of the three-dimensional mirror with respect to an optical axis of the light focused with a lens, which allows optical axis shift of the reflected light to be corrected in the three-dimensional mirror according to setting of a chromatic dispersion compensation amount.

Abstract: Beams inputted from a fiber are collected by a lens and are angular-dispersed by a VIPA. The luminous flux from the VIPA is collected on a surface-shape variable mirror by a lens. The surface-shape variable mirror is configured in such a way that a mirror shape can be controlled by a piezo stage and necessary wavelength dispersion can be applied, if necessary. Although the beam group reflected on the surface-shape variable mirror propagates the light path backward, the beam group is inputted to a position different from the outputted position when the beam group enters the VIPA. Therefore, a desired wavelength dispersion can be given to each beam group by performing control of the input position in the VIPA for each wavelength using the surface-shape variable mirror.
