摘要： In the condition that an acrylic transparent vessel is filled with a curable resin solution capable of being cured by a light, a plastic optical fiber is immersed in the curable resin solution. A laser beam is applied on the curable resin solution through the plastic optical fiber. The curable resin solution is cured gradually by the laser beam applied on the curable resin solution, so that an axial core is formed. Then, the transparent vessel is left at rest for predetermined time, or uncured part of the curable resin solution is removed from the transparent vessel and the transparent vessel is then filled with another curable resin solution. Then, ultraviolet rays are applied on the transparent vessel from the outside of the transparent vessel to cure the residual uncured part of the curable resin solution.

摘要： [Object] A self-written branched optical waveguide is formed.[Solving Means] A laser beam 2 from a laser source (not shown) is focused with a lens 3 onto the face of incidence 10 of an optical fiber 1. The laser beam of an LP11 mode was emitted from the face of emergence 11, and “bimodal” light intensity peaks were arranged in the horizontal direction (1.A). A slide glass 4 coated with a photocurable resin gel 5 was placed horizontally (1.B). A single linear cured material 61 was formed as the LP11-mode laser beam was emitted from the face of emergence 11 of the optical fiber 1 (1.C). A branch portion 62 was then formed at a distance L from the face of emergence 11 of the optical fiber 1, which was followed by the growth of two cylindrical cured materials 63a and 63b. The two cylindrical cured materials 63a and 63b were linear branches, and formed an angle of about four degrees. An optical waveguide 60 thus formed was composed of cured materials 61, 62, 63a, and 63b (1.D).

摘要： Interference filters which are optical components are erected in advance on optical paths in a transparent container, and the transparent container is filled with a photo-curable resin solution. Further, a jig is prepared for manufacturing an optical waveguide device. The jig includes a housing, and holes. On this occasion, positions of the holes are set such that light input through the hole reaches the holes via the interference filters. Optical fibers are fitted into the holes of the housing and the housing is mounted on the transparent container. Next, light at a predetermined wavelength is guided into the optical fibers so that optical waveguides are formed in the photo-curable resin solution. Next, the photo-curable resin solution is exchanged for a low-refractive-index photo-curable resin solution and then the low-refractive-index photo-curable resin solution is solidified wholly by ultraviolet light. Finally, for example, an optical fiber, a light-receiving element, etc. are provided.

摘要： Disclosed is a light attenuator comprising a stick or rod composed of a light-transmitting material, and a light-attenuating layer composed of a thermoplastic resin and formed on at least one end face of the stick or rod, wherein finely divided particles having a light-absorbing or light-scattering property are uniformly incorporated in the thermoplastic resin. This light attenuator is made by forming a light-attenuating thermoplastic resin layer having incorporated therein the light-absorbing or light-scattering finely divided particles on a release film or paper; placing the light-attenuating layer formed on the release film or paper on a heating plate; press-bonding the end face of a rod or stick composed of a light-transmitting material inserted and set in a ferrule to the surface of the release film or paper; cooling the bonded assembly; and then peeling the release film or paper to transfer the light-attenuating layer to the end face of the light-transmitting rod or stick.

摘要： Transparent parallel planar plates which are members for retaining an optical waveguide are provided erectly in an optical path of light in a transparent vessel in advance. An optical fiber is fixed into the transparent vessel while the optical fiber penetrates the transparent vessel, and an optical sensor is also disposed adjustably. Next, a first photo-curable resin solution is injected into the transparent vessel, and light with a predetermined wavelength for curing is emitted from the optical fiber so that the optical waveguide is self-formed by polymerization reaction. Because the parallel planar plates are transparent, the optical waveguide is formed so as to be extended again from the emission ports of the parallel planar plates. Finally, the optical waveguide is formed so as to reach a bottom surface of the transparent vessel. The optical waveguide has a structure in which the optical waveguide is firmly supported at four points in a forward end surface of the optical fiber, the parallel planar plates and the bottom surface of the transparent vessel. Accordingly, a firm optical waveguide device is formed.
