    • 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.
    • 从纤维输入的光束由透镜收集,并通过VIPA进行角度分散。 来自VIPA的光通量由透镜收集在表面形可变镜上。 表面形状可变镜被配置为可以通过压电级控制镜面形状,并且如果需要可以应用必要的波长色散。 尽管反射在表面形状可变镜上的光束组向后传播光路,但当光束组进入VIPA时,光束组被输入到与输出位置不同的位置。 因此,可以通过使用表面形状可变镜对每个波长的VIPA中的输入位置进行控制,可以对每个光束组给出期望的波长色散。

    • A washing machine that facilitates and simplifies the breaking up of the washing machine to recycle or re-use the components thereof and the method of breaking up the washing machine. A plurality of upper receptors are provided in the upper inside of the housing. A plurality of lower receptors are provided in the lower outside of the washing-tub assembly. The upper and lower receptors are linked by rolls to constitute a suspension mechanism. Each rod has an upper support and a lower support at the upper and lower ends, both supports are larger than the rod in diameter. With the upper supports engaged with the upper receptors and the lower supports with the lower receptors, the washing-tub assembly is suspended within the housing. A recess is formed on the top of upper receptor. The bottom of the recess is provided with a hole and a slit that is a path to the hole. The diameter of the hole and the width of the slit are set in such a way that the rod is allowed to pass but the upper support is not allowed to. A retainer is provided at the slit. This retainer can selectively take either one of two positions—the first position in which it retains said rod in said hole, and the second position in which it allows the rod to get into or get out of said hole through said slit. By shifting the retainer from the first position to the second position, the rod can be removed from the first receptor without raising the washing-tub assembly.

    • 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.

    • 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.
