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： A probing device includes a minute probe in which at least an end portion is formed by conductive material, a cantilever having one end to which the probe is attached, and another end fixed to a moving member movable relatively to a sample in each direction of X, Y and Z, a unit for moving the moving member relatively to the sample, a transducing unit for generating information of voltage or current by means of light, a connecting unit having a low electric resistance, for connecting the transducing unit and the end portion of the probe, a detecting unit for detecting a change in a physical amount occurring in the cantilever by a force caused between the probe and the sample by a relative proximity of the moving member to the sample, and a voltage measuring unit for measuring a voltage at a measurement point on the sample, which is determined based on an output of the detecting unit, by way of the transducing unit when the probe is contacted with the measurement point. By the constitution, it is possible to realize a voltage measurement with both an enhanced space resolution and an enhanced time resolution. Also, by using the probing device in an integrated circuit testing apparatus or system, it is possible to realize a stable probing to a minute wiring without increasing an electrical load with respect to the minute wiring and thus contribute to an improvement in the precision of a voltage measurement.

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.
