摘要： The optical reflective filter is made from a photosensitive optical fiber having a cladding and a core including germanium. Refractive index perturbations are light induced in the fiber in the region of the guided light. The perturbations can be made to have a constant or a varying periodicity, or a series of constant periodicities. The filters are made from single mode or low order mode fibers having germanium doped silica or germania cores. The center frequency for reflective band or bands has a wavelength in the 400 nm to 550 nm range. The reflective band or bands in the filter can be shifted by stretching the filter.

摘要： In an optical fiber system comprising first and second polarization-maintaining fibers, a first orthogonal coordinate system of the first polarization-maintaining fiber is azimuthally rotated relative to a second orthogonal coordinate system of the second polarization-maintaining fiber by the use of an optical coupler by a preselected angle between 0.degree. and 90.degree., both exclusive. Preferably, the optical coupler is shorter than a beat length of each fiber and the preselected angle is equal to 45.degree.. The optical fiber system is applicable to an optical sensor for sensing a variable physical parameter. In the sensor, a light beam is incident onto one end of the first polarization-maintaining fiber so that a plane of polarization of the light beam is matched to one of those planes of the first polarization-maintaining fiber which are determined by the first orthogonal coordinate system. A third polarization-maintaining fiber is coupled through an additional optical coupler to the second polarization-maintaining fiber. The optical fiber system can be manufactured either by twisting and locally fusing a single polarization-maintaining fiber or by splicing together two polariation-maintaining fibers.

摘要： An optical branching element mainly composed of a central linear optical transmission line and a plurality of peripheral linear optical transmission lines. They have circular sections of approximately the same diameters. The peripheral linear optical transmission lines are provided around the central linear optical transmission line such that their end surfaces are arranged on the same plane as the end surface of the central linear optical transmission line. A holder fixes these central and peripheral linear optical transmission lines on the end surface side. Semispheric reflecting concave surfaces having radii larger than the diameters of said peripheral linear optical transmission lines are formed around the contact points of the end surface of the central linear optical transmission line and the end surfaces of the linear optical transmission lines. A reflector which is provided in opposed contact with the contacting surface of the holder incorporates a plurality of semi-spherical reflecting concave surfaces as a reflecting concave surface.

摘要： An optical wavelength demultiplexer includes a retainer means which curvedly retains an optical fiber. A mirror-polished surface is formed on the convex side of a curved portion of the optical fiber which is retained by the retainer means in such a manner that the mirror-polished surface is in close proximity to the core of the optical fiber. Further, a diffraction grating is disposed such as to oppose and contact the mirror-polished surface. The pitch of the diffraction grating is set to be .lambda./2n.sub.f, where .lambda. represents the wavelength of light to be separated, and n.sub.f the effective refractive index of the optical fiber. The direction of the pitch is selected to be coincident with the extending direction of the optical fiber.

摘要： A directional coupler for coupling two single-polarization optical fibers each comprising a core, a cladding, and an elliptic jacket having a major axis is made by preparing two quartz substrates each of which is formed with a channel on one major surface; embedding and bonding the jacketed single-polarization optical fibers in the channels in the substrates, respectively, such that the major axis of the elliptic jacket extends perpendicular to the substrate surface; abrading away the substrates together with the fiber embedded therein from the major surface to a depth where light traveling in the core of said fiber may leak out; placing one substrate on the other substrate with the abraded surfaces facing each other; and bonding the substrates to keep the cores in sufficiently close relation to establish evanescent wave coupling therebetween. A stress perpendicular to the major axis is preferably applied to the fiber.
