摘要： The present invention provides a light-receiving device that may escape the device from the breakdown thereof and may suppress an optical loss. The light-receiving device of the invention includes a surface to sense the light and a thin film made of PbSe nano-particles, diameters of which are smaller than 20 nm. This thin film operates as an optical fuse, so the device may be escaped from the breakdown thereof. Moreover, the thin film is disposed directly onto the light-sensing surface of the device, the optical loss cause between the thin film and the sensing surface may be suppressed.

摘要： The present invention provides a line transition and a method for manufacturing the same. The line transition is constructed such that a planar circuit can be arranged in the direction parallel to the propagation direction of electromagnetic waves propagating through a solid waveguide, the coupling characteristics of the solid waveguide with the planar circuit formed on a dielectric substrate are not influenced by the assembly precision of the waveguide and the circuit, and the line transition characteristics are not affected by a variation in manufacturing the dielectric substrate. Notches are formed at the edges of the dielectric substrate in the vicinities of coupled-line pattern segments formed on a dielectric substrate. The notches are formed by punching through holes in a ceramic green sheet serving as a motherboard, firing the motherboard, and cutting the motherboard using dicing lines passing through the through holes.

摘要： Electrodes are formed on respective two main surfaces of a dielectric sheet wherein each electrode has an opening formed at a location corresponding to the location of the opening formed in the other electrode. The part defined by the openings serves as a dielectric resonator. Coupling lines are formed directly in the electrode opening. Transmission lines are formed on a circuit board. The coupling lines and the corresponding transmission lines are connected to each other via bonding wires. This structure makes it possible to minimize the external Q of a resonant circuit using the dielectric resonator. If an oscillator is produced using this resonant circuit, it is possible to achieve a large frequency modulation with and large output.

摘要： This invention relates to a single-mode optical fiber having a configuration for effectively reducing bending loss. In the single-mode optical fiber, while an optical core is constituted by inner and outer cores, an optical cladding is constituted by an inner cladding in which "tailing" occurs and an outer cladding. In particular, in a cross section of the optical fiber perpendicular to the signal light guiding direction, when the surface integral values of relative refractive index difference of the optical cladding and optical core with respect to the outer cladding having an average refractive index n.sub.0 are respectively S1 and S2, the optical fiber satisfies a relationship of S1/S2.gtoreq.0.8.
