摘要： An object of the invention is to provide a mirror fixing method capable of reducing stress distortion of a surface of a mirror which constitutes an optical system, with hardly deforming a surface shape of the mirror. To this end, the present mirror fixing method is characterized in that a mirror part including a base plate formed with a mirror on one face thereof, is provided with a boss on the other face of the base plate opposite to the face on which the mirror is formed, and only the boss is fixed, so that the mirror part excluding the boss is not in contact with other members.

摘要： 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. The control section computes a target position of the three-dimensional mirror and the target temperature of the VIPA plate, which correspond to an arbitrary wavelength and a chromatic dispersion value, based on data relating to positions of the three-dimensional mirror corresponding to a plurality of chromatic dispersion values of a specific wavelength and a chromatic dispersion slope value, and data relating to the temperatures of the VIPA plate corresponding to a plurality of dispersion values for respective wavelengths on a predetermined wavelength grid and a wavelength temperature coefficient, which are stored in a storage circuit, to optimize the computed target position and the computed target temperature. As a result, it becomes possible to generate the chromatic dispersion with high accuracy at an arbitrary wavelength.

摘要： 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.

摘要： 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. Accordingly, chromatic dispersion compensation and dispersion slope compensation can be realized over a wide signal band.
