    Abstract: An optical device includes an optical element (300), a detector (303) and a controller (304). The optical element (300) has an optical waveguide (301). The refractive index of the optical waveguide (301) is controlled by a heater (302). The temperature of the optical element (300) is controlled by a temperature control device. The detector (303) detects the current flowing in the heater (302) and/or the voltage applied to the heater (302). The controller (304) then controls the electrical power provided to the heater (302) so as to keep it constant, according to the detection result of the detector (303). This obviates the need for a temperature detector.

    Abstract: The present invention discloses a widely wavelength tunable polychrome colloidal photonic crystal device whose optical Bragg diffraction stop bands and higher energy bands wavelength, width and intensity can be tuned in a continuous and fine, rapid and reversible, reproducible and predictable fashion and over a broad spectral range by a controlled expansion or contraction of the colloidal photonic lattice dimension, effected by a predetermined change in the electronic configuration of the composite material. In its preferred embodiment, the material is a composite in the form of a film or a patterned film or shape of any dimension or array of shapes of any dimension comprised of an organized array of microspheres in a matrix of a cross-linked metallopolymer network with a continuously variable redox state of charge and fluid content. The chemo-mechanical and electro-mechanical optical response of the colloidal photonic crystal-metallopolymer gel is exceptionally fast and reversible, attaining its fully swollen state from the dry shrunken state and vice versa on a sub-second time-scale. These composite materials can be inverted by removal of the constituent microspheres from the aforementioned colloidal photonic crystal metallopolymer-gel network to create a macroporous metallopolymer-gel network inverse colloidal photonic crystal film or patterned film or shape of any dimension optical Bragg diffraction stop bands and higher energy bands wavelength, width and intensity can be redox tuned in a continuous and fine, rapid and reversible, reproducible and predictable fashion and over a broad spectral range by a controlled expansion or contraction of the colloidal photonic lattice dimensions.

    Abstract: An ultrasonic receiving apparatus in which ultrasonic wave signals can be detected in a two-dimensional manner without necessities of electric-wiring works to a large number of very fine elements, and without increase of crosstalk and impedance. The ultrasonic receiving apparatus can be manufactured in low cost. This ultrasonic receiving apparatus includes an ultrasonic detecting element 20 having a reception plane capable of receiving ultrasonic waves, for modulating light on the basis of ultrasonic waves applied to the respective positions of the reception plane; and a photodetector 16 having a plurality of pixels, for detecting light output from corresponding positions of the ultrasonic detecting element.

    Abstract: A substrate for reflection type liquid crystal display elements is provided, which has a multilayer dielectric film (reflective mirror) which can have fewer layers than according to the conventional art and can thus be formed in a shorter time, and which can stably obtain an optical characteristic of a desired flatness across the visible region, and moreover can prevent the occurrence of coloring due to reflection. The reflective mirror is formed on top of a transparent substrate, and is comprised of a predetermined number of high-refractive-index first transparent films and low-refractive-index second transparent films laminated alternately on the transparent substrate. Either or both of the first transparent films and the second transparent films are arranged such that the film thickness thereof increases progressively or decreases progressively with distance from the transparent substrate.
