摘要： In an optical monitor for monitoring signal lights from a plurality of optical fibers, emission surfaces of the plurality of optical fibers are arranged along a straight line, and a photodetecting surface of a photodetecting element disposed so as to face the emission surfaces is moved in parallel to the straight line along which the emission surfaces are arranged in such manner that light from each of the emission surfaces is received by the photodetecting element, so that the plurality of signal lights are made incident on the photodetecting element successively. The present optical monitor thereby is capable of monitoring a large number of transmission paths while requiring a small number of components.

摘要： An optical communication system is designed to suppress the generation of cross talk even in the case of small wavelength spacing and high bit-rate modulation. An Nth order harmonic generating device where N is an integer of 2 or larger is positioned before a demultiplexer to upconver the frequency or down convert the wavetlength of the light wave by N times. The frequency spacing between the carriers is increased and allows easier separation of the optical signal and permits denser WDM channels and/or higher data rate per channel. In addition, Si or GaAs based photodiodes may be used instead of InP based photodiodes since the 1550 nm bands are converted to 780 nm bands.

摘要： An optical circuit is designed with demultiplexing and optical detection functionality with minimal crosstalk. An Nth order harmonic generation device is positioned before the demultiplexer to either convert the frequency or down convert the wavelength of the demultiplexed light wave by N-times. Upconverting the multiplexed signal at the receiver station is performed by either simultaneously upconverting N-times to create N times the original spacing between each optical channel or by upconverting the frequency of one optical channel at a time.

摘要： In a plate microlens of the invention, wherein gradient index lenses each having an optical axis along a normal to a surface of a transparent base and a refractive index profile gradually changing along a direction of the optical axis and a direction perpendicular thereto are formed integrally in the transparent base; a ratio d/a (where d is a thickness of the gradient index lens on the optical axis and 2a is a diameter of the gradient index lens on a surface of the transparent base) falls within a range of 0.46 to 0.78. In a method for manufacturing a plate microlens of the invention, of forming integrally in a transparent base, gradient index lenses with a gradient index profile based on a concentration gradient of a substance for increasing the refractive index of the transparent base, by forming a diffusion preventive mask with predetermined apertures on a surface of the transparent base and diffusing the substance into the transparent base through the apertures; a ratio a/rm (where rm is a radius of the apertures and a is a radius of the gradient index lenses to be formed) satisfies a relation 1.75.ltoreq.a/rm.ltoreq.4.5.

摘要： It is possible to compatibly set multiple “dropout” color ranges and “non-dropout” color ranges and uniquely determine a dropout boundary. An object of the present invention is to greatly conserve maintenance cost of adding a new dropout form after apparatus operations. A conventional technology aims at assuring relation to a predetermined color region, determining the presence or absence of contention, or uniquely settling a dropout boundary. The present invention provides a means for supplying levels to a “dropout” color range and a “non-dropout” color range. A registered color range histogram can be quasi-three-dimensionally visualized so that an operator can make adjustment by viewing a contention determination result and an image.

摘要： A light detection device for detecting an optical path position of invisible light. The detection device includes a main body and a light guide. The light guide includes a distal end functioning as a light incident portion through which the detected light enters and a light radiation portion from which visible light is emitted. A drive mechanism reciprocates the light guide in an X-direction while vibrating the light guide in a perpendicular Y-direction. The distal end of the light guide rod moves within a light detection area in an XY plane. A visible light-emitting unit radiates visible light from the distal end when the detected light enters the distal end. The visible light-emitting unit includes a photo-detector for detecting the detected light and a light-emitting element for generating the visible light when the photo-detector detects the detected light.

摘要： In an optical system in which light output from an optical fiber (11) is collimated into parallel light rays by a gradient index rod lens (13), reflected by a filter (4) and then converged again by the rod lens (13) so that the resulting light is coupled to an optical fiber (12), a principal beam component of the light output from the optical fiber (11) disagrees with an optical axis (32) of the optical fiber (12) to thereby cause a coupling loss. When W is the distance between optical axes (31 and 32) of optical fibers (11 and 12) and Z is the length of a rod lens (13) on an optical axis (33) of the rod lens, the optical fibers (11 and 12) and the rod lens (13) are disposed to satisfy the condition: W·g·(0.25−Z/P)2≦6×10−5 in which g is a gradient index distribution coefficient of the rod lens, and P is the periodic length of the rod lens (13).

摘要： A surface of a substrate is coated with a sol solution containing metal alkoxide. A gelled material of the sol solution is pressed against a molding tool while the gelled material is kept soft. Thus, the gelled material is molded. Then, the gelled material is hardened. As a result, protrusions of the hardened gel layer 14 are formed on the substrate so that an irregular texture substrate is formed. A multilayer thin film constituted by a plurality of layers of at least two kinds of materials with different refractive indexes is laminated on a surface of the irregular texture substrate.
