Abstract: A reconfigurable polarization rotator is formed of an array of very small liquid crystal (LC) cells (e.g., cells of less than 10 μm in width, termed “microcells”), referred to hereinafter as “microcells”. Each LC microcell is addressable by a separate electrical voltage input that independently controls the polarization rotation performed by the associated LC microcell. By defining a set of adjacent microcells to be held at the same voltage level, that group may be used to form a polarization rotator window of a proper size for a first fiber array configuration. When a fiber array of a different configuration (say, an array with twice the pitch) is used, a different-sized group of adjacent LC microcells is held at a common voltage level so as to form a reconfigured “window” of a new dimension.

Abstract: An optical waveguide element includes a substrate, an optical waveguide disposed inside the substrate or on the substrate, and an electrode provided along the optical waveguide, working on the optical waveguide to generate a phase change in a light wave propagating through the optical waveguide. The electrode is a traveling-wave electrode. In a modulation section where the light wave is controlled by the electrode, the electrode and the optical waveguide are configured so that the phase change generated in a first modulation section located within a predetermined distance range from a downstream side end portion along a propagation direction of a traveling wave of an electrical signal propagating through the electrode has a sign opposite to a sign of the phase change generated in a second modulation section located within a predetermined distance range from an input end of the electrical signal on an upstream side along the propagation direction.

Abstract: A liquid crystal panel and a cross-shaped spacer structure thereof are disclosed. The liquid crystal panel includes an array substrate, a color filter substrate, and a cross-shaped spacer structure sandwiched between the array substrate and the color filter substrate. The cross-shaped spacer structure includes a plurality of strip-like first spacers disposed on the upper surface of the array substrate and a plurality of strip-like second spacers disposed on the lower surface of the color filter substrate. The end surface of each one of the strip-like first spacers and the end surfaces of each three of the strip-like second spacers are abutted against each other in a cross manner. Thus, when the liquid crystal panel is impacted by external force, the strip-like first spacers and the strip-like second spacers can keep a tight abutment therebetween, so as to ensure the display quality of the liquid crystal panel.

Abstract: Problems To provide a method for evaluating characteristics of MZ interferometers in an optical modulator having a plurality of MZ interferometers.Means for Solving Problems When an optical modulator includes a plurality of MZ interferometers, the 0-degree component contains a signal derived from an MZ interferometer other than the MZ interferometers for evaluating the characteristic. For this, it is impossible to accurately evaluate the characteristic of the MZ interferometers. The present invention does not use the 0-degree component normally having the highest intensity. That is, the characteristic of the MZ interferometers are evaluated by using a side band intensity of the component other than the 0-degree component.
