を特徴とする光フアイバカプラ。 It consists of an optical fiber consisting of a cladding and a core part, and a substrate having a groove for burying the optical fiber formed with a predetermined radius of curvature in the depth direction of the surface, and the groove having the radius of curvature is used for burying/fixing the optical fiber. When the top of the cladding along the curved surface is at a depth slightly lower than the surface of the substrate, the surface on the side where the optical fiber is buried is polished together with the cladding to remove it several μm before the core is exposed; In an optical fiber coupler in which two of the substrates are fixed as a set and the clads on the polished sides are brought into contact with each other and fixed, at least one of the substrates near where the optical fiber is fixed/buried is formed into a convex shape.
