摘要： PROBLEM TO BE SOLVED: To provide a method suitable for coupling an optical connecting component to an optical fiber in the place where an optical connector is used.
SOLUTION: In the method for assembling the optical connecting component in which an optical fiber 6 is fixed by using an adhesive and a hardener 51 in a fixing hole 3a of the optical connecting component, the hardener 51 is deposited on the inner wall face of the fixing hole 3a. Consequently, the hardener can be made ready in a number of regions in the inner wall face of the fixing hole 3a. Even if the surface of the optical fiber 6 is of a material to easily repel the hardener, a sufficient adhesive strength is obtained.

摘要： PROBLEM TO BE SOLVED: To provide a multilayer optical waveguide with grooves in which polarization dependency of a coupling rate is reduced. SOLUTION: This multilayer optical waveguide is constituted by laminating a lower cladding layer 2, a lower core 21, an intermediate cladding layer 4, an upper core 22, and an upper cladding layer 6 on a silicon substrate 1. Then, an interlayer optical directional coupler having an optical coupling straight part 7 is constituted by the upper and lower cores 21, 22. Moreover, in the optical coupling straight part 7, grooves 23, 24 are formed along the cores 21, 22 at both sides of them. Depth of the grooves 23, 24 reaches the base of the lower cladding layer 2 from the surface of the upper cladding layer 6. Thereby, stress in the horizontal direction of the substrate can be released and the coupling rate of this optical waveguide becomes the same coupling rate even when light is a TM polarized wave or a TE polarized wave.

摘要： PROBLEM TO BE SOLVED: To provide a method for assembling a single fiber optical connector capable of rapidly assembling it.
SOLUTION: The method for assembling the single core optical connector comprises inserting a bare part 33a of an optical fiber 33 into an optical fiber insertion bore disposed in the central part of a ferrule 31 of the optical connector and fixing the optical fiber 33 and the optical fiber insertion bore by using an adhesive. A cyanoacrylate system instant adhesive 32 and an amino system curing accelerator 34 are used as the adhesive. After the accelerator 34 is applied to the optical fiber 33 and is dried, the optical fiber is inserted into the ferrule 31 of the optical connector and the optical fiber 33 is bonded and fixed to the ferrule 31 by using the instant adhesive 32. As a result, the optical connector having good reliability can be rapidly and easily assembled without using a specific apparatus and therefore the efficient assembly of the optical connector is made possible.
