摘要： High-frequency couplers and coupling techniques are described utilizing artificial composite right/left-handed transmission line (CRLH-TL). Three specific forms of couplers are described; (1) a coupled-line backward coupler is described with arbitrary tight/loose coupling and broad bandwidth; (2) a compact enhanced-bandwidth hybrid ring coupler is described with increased bandwidth and decreased size; and (3) a dual-band branch-line coupler that is not limited to a harmonic relation between the bands. These variations are preferably implemented in a microstrip fabrication process and may use lumped-element components. The couplers and coupling techniques are directed at increasing the utility while decreasing the size of high-frequency couplers, and are suitable for use with separate coupler or couplers integrated within integrated devices.

摘要： An optical fiber of which one end is optically coupled to a laser light source propagating, from the one end to other end, a laser light emitted from the laser light source. A light-guiding plate includes a light-guiding section in which a plurality of right prisms of the same shape for extracting the laser light by contacting the optical fiber are arranged parallel to each other in the same direction at equal intervals. A planar section diffuses the laser light extracted from the light-guiding section and emits the diffused laser light from one main surface. The optical fiber is bent more than twice to form a plurality of straight line portions arranged parallel to each other at unequal intervals, and the optical fiber and the light-guiding plate are positioned such that the laser light is extracted at equal intervals from each of the plurality of straight line portions.
