    摘要： An optical system comprising a substrate and an optical waveguide which is formed on the substrate and to which optical fibers are optically coupled. The optical waveguide has a plurality of straight core portions which obliquely intersect each other. The substrate has positioning sections for positioning a plurality of optical fibers optically coupled to two or more of the plurality of the core portions, the positioning sections having grooves on which the respective optical fibers are supported. When the plurality of optical fibers are supported on the respective grooves, offsets between centers of the plurality of the core portions and respective centers of the plurality of the optical fibers coupled to the core portions are equal to or less than 5 μm.

    摘要： An optical waveguide structure (6) comprises a substrate (12) having a first groove array (8) and a second groove array (10) which are longitudinally spaced from each other, and an optical waveguide (14) layered on the substrate (12) between the first and second groove arrays (8, 10). Each groove array (8, 10) includes a plurality of grooves (8a-8g, 10a-10h) extending longitudinally and arranged laterally relative to each other. The optical waveguide (14) has a cladding layered on the substrate (14), and a core (14b) formed on the cladding so that, when optical fibers (2, 4) are supported and positioned on the grooves (8a-8g, 10a-10h) of the first and second groove arrays (8, 10), the core (14b) of the optical waveguide (14) is aligned with cores (2a, 4a) of the optical fibers (2, 4) at the same level in an vertical direction. In order to allow light transmission between optical fibers (2, 4) positioned at the respective first and second groove arrays (8, 10), the optical waveguide (14) has at least one first port (20) aligned with a groove (8d) of the first groove array (8), and at least one second port (22) aligned with a groove (10e) of the second groove array (10). The number of the second port (22) is equal to or greater than that of the first port (20). A ratio of the number of the grooves (10a-10h) of the second groove array (10) relative to the number of the grooves (8a-8g) of the first groove array (8) is less than a ratio of the number of the second ports (22) relative to the number of the first ports (20).
