    • An optical waveguide structure comprises a substrate (12) having first and second groove arrays (8, 10), including grooves (8a-8g, 10a-10h), and an optical waveguide (14), having cladding and core (14b) layered on the substrate between the groove arrays to vertically align the core with cores (2a, 4a) of optical fibers (2, 4) positioned on the grooves. The waveguide has at least one first port (20) aligned with a groove (8d) of the first groove array and at least one second port (22) aligned with a groove (10e) of the second groove array. The number of second ports is equal to or greater than that of the first ports. A ratio of the number of grooves of the second groove array relative to the number of grooves of the first groove array is less than a ratio of the number of the second ports relative to the number of first ports.

    • An optical waveguide having an effect resulting from a size reduction such as an increase in the number of fetches, because it has no substantial rise in the manufacturing cost but can reduce the size, and an optical system including the optical waveguide. The optical system includes first, second and third optical input/output means (12, 14 and 16), fourth and fifth multimode optical waveguides (20 and 22) capable of transmitting a light in multiple modes, and optical filter mounting means (26) for mounting an optical filter (24) between the fourth and fifth multimode optical waveguides (20 and 22) in a direction to intersect the traveling direction of the light in the fourth and fifth multimode optical waveguides. The optical system is characterized in that the fourth and fifth multimode optical waveguides (20 and 22) have different widths in a direction perpendicular to the light traveling direction. ® KIPO & WIPO 2007
    • 由于其制造成本没有实质上的提高而导致尺寸减小以及包含光波导的光学系统,所以具有由诸如提取次数增加而引起的尺寸减小的效果的光波导。 该光学系统包括第一,第二和第三光学输入/输出装置(12,14和16),能够传输多种模式的光的第四和第五多模光波导(20和22)和滤光器安装装置(26) 用于在与第四和第五多模光波导中的光的行进方向相交的方向上在第四和第五多模光波导(20和22)之间安装滤光器(24)。 光学系统的特征在于,第四和第五多模光波导(20和22)在垂直于光行进方向的方向上具有不同的宽度。 ®KIPO&WIPO 2007

    • An optical waveguide structure having a multiplexing/demultiplexing section. The optical waveguide structure (150) has a first core part (A1) on the multiplexing side formed along a first axis (LA1) curved to one side (S1), a second core part (B1) on the demultiplexing side formed along a second axis (LB1) curved to the one side (S1), and a third core part (C1) on the demultiplexing side formed along a third axis (LC1) curved to the other side (S2). The axes (LA1, LB1, LC1) have contacts (PA1, PB1, PC1) touching the respective tangents parallel to each other.
