摘要： PROBLEM TO BE SOLVED: To inexpensively provide a waveguide optical switch capable of controlling high-speed and large-capacity communications by low voltage drive. SOLUTION: A waveguide optical switch is created by using whisker electrodes utilizing ZnO whiskers, forming a flat buffer layer on the tip parts of whiskers, forming waveguides on the surface of the buffer layer by silk printing or the like, and arranging the other counter electrode.

摘要： PROBLEM TO BE SOLVED: To enhance sensitivity and resolution in fluorometric measurement using a DNA chip, or a protein chip, making the best use of a basic technique for an existing femto-second confocal microscope.
SOLUTION: A measuring system of high detection S/N ratio is realized, using two kinds of fluorescences different in fluorescence spectrum, in which the fluorescence spectra are crossed not in peak positions of the fluorescences but in wavelengths sided to foots thereof, and using as a light source for an excitation beam a femto-second pulse laser beam of which the wavelength is varied periodically around a crossing position as the center, and high-resolution of observation is attained using a two-photon or multiple-photon absorbing process.

摘要： PROBLEM TO BE SOLVED: To resolve the problem that costs cannot be considerably reduced as a result of the necessity for a connection connector or the like because even a plastic optical waveguide has light input/output parts manufacturd by conventional connection techniques though development of optical parts using inexpensive plastics are expected in order to spread optical communication environments up to ordinary homes. SOLUTION: An optical waveguide is so constituted that an optical fiber having the end face worked is fixed to the end part on an optical axis and a thermosetting resin is made to flow onto a substrate up to such a degree that the end face of the optical fiber is sufficiently immersed in the resin. Ultraviolet rays or the like are radiated from the rear of the substrate to simultaneously complete the forming of the optical waveguide and the fixing of the optical fiber. Thus the optical waveguide with the optical fiber can be integrally formed to reduce the light loss and the manufacturing cost of a connection part. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To solve the problem wherein it has not been possible to obtain a manufacturing facility which does not require a vacuum device which supplies at a low price by mass-production optical circuit components such as an optical waveguide used to lay an optical fiber communication system into respective homes, as can give high dimensional precision and high reliability, and can incorporate even a large-area component on the back. SOLUTION: The optical circuit component is produced by using an ink which is transparent to signal light after setting and has a larger refractive index than a substrate and air and drawing the optical circuit component directly on the substrate by a printing technique. Variation in the shrinkage rate, the contact angle with the substrate, etc., of the ink are variously devised. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a method for maintaining strength enough to keep a three dimensional positioning of a crystal material having an acicular form without damaging its function by reinforcing adhered parts by any means. SOLUTION: For the purpose that an uncured resin has to be well impregnated into spaces among aggregated whisker, the resin is preferably low viscous and well compatible with ZnO, which is a material of the whisker, and further the resin is necessary to be a non-solvent type in order to suppress volume shrinkage upon curing. Further, the volume shrinkage upon curing can be prevented by selecting/designing a resin generating no releasing group upon curing (e.g. an epoxy resin). Still further, a resin having a high hydrophilicity such as one having a large amount of an OH group is selected for impregnation because the surface of ZnO is generally hydrophilic due to influence by moisture in air. A linear expansion coefficient of the resin used is adjusted to one similar to that of the whisker by mixing the resin with particulates having a low thermal expansion coefficient.
