An organic compound having an affinity for a resin of a molded resin article and sublimation properties is allowed to penetrate/disperse into the surface of the molded resin article, thereby modifying and/or coloring a resin surface layer. The molded resin article and the organic compound having the affinity for the resin and the sublimation properties are put into a tightly closable container, and the pressure and the temperature in the container are adjusted to place them in a saturated sublimation pressure state of the organic compound, whereby a vapor of the organic compound is uniformly deposited on the surface of the molded resin article and it further penetrates/disperses into the resin surface layer, and in consequence, the resin surface layer can be modified and/or colored. In addition, the modification of the resin surface layer permits imparting a function thereto.

An optical element, optical control device and optical control method are provided which demonstrate a large, rapid optical response using a laser light of low output as a control light. A signal light is emitted from an optical source . A signal light emitted from an optical source A control light and the signal light are converged by a condenser lens and irradiate an optical element Only the signal light is detected by a photodetector through a light receiving lens and a wavelength selection filter A thermal lens is formed reversibly in the optical element and switching the control light ON and OFF modulates the intensity of the signal light. The optical element has a laminar structure comprising a heat transfer film/heat insulation film/light absorption film/heat insulation film/heat transfer film, for example, and a sufficiently large and rapid optical response is obtained using low output laser light as the control light by adjusting the thickness of the light absorption film so that it does not exceed twice the confocal length of the converged control light.

A thin-film fabrication method includes a spray step in which at least one thin-film composition material in liquid form is sprayed into a vacuum vessel via a spray nozzle provided for each thin-film composition material and deposited on a substrate, and a heat treatment step in which the material deposited on the substrate is heat treated. The substrate temperature in the spray step and/or the heat treatment step is controlled within a prescribed temperature range.

Thin-film fabrication method and apparatus

An optical probe is used in a near-field effect microscope for performing topographical observation and physical property measurement on a surface of a sample. The optical probe comprises an optical resonator having an optical fiber having at least one microscopic projection composed of a dielectric material disposed at an end portion of the optical fiber for transmitting light.

An optical computer includes a plurality of functional elements (thin-film elements) each adapted for causing an external signal to act on a two-dimensional-information incident light so as to perform information processing, and light sources for transferring the two-dimensional-information incident light between the functional elements. Each of the functional elements includes nanoparticles comprising molecules of an organic compound and associates/aggregates of these molecules. This structure makes it possible to input light beams from a plurality of functional elements to a single functional element and to output light beams from this single functional element to the plurality of functional elements.

Optical computer

A full optical type optical element performs an information processing on an input signal light beam through use of only light beams including the signal light beam and an auxiliary light beam for assisting operation. The optical element includes aggregates which are dispersed within the optical element as optical functional aggregates, and which are composed of a single kind or multiple kinds of compounds including a single species of atoms or molecules. Thus, a full optical type optical element having a high resolution can be obtained through use of a thin-film element which contains nanoparticles comprising molecules of an organic compound and associates/aggregates of these molecules.

Full optical type optical element

A process for producing thin films includes a step of dissolving one or two or more thin film materials into solutions or dispersions that are sprayed respective spray nozzles provided for each component onto a substrate in a high vacuum vessel. The components are deposited on the substrate and then are heated.
