    Abstract: Provided is a lens holder, a lens optical component, or a package equipped with the lens optical component, in which poor welding between a lens housing and the lens holder may not occur. A lens holder includes a pair of leg members inclined and extending to a lens housing from a support member that supports the lens holder at a predetermined position. A distance between pair of leg members is set such that the distance between lower end portions is equal to or larger than a width of the lens housing to be supported, and the distance between upper end portions is equal to or smaller than the width of the lens housing to be supported, and that the distance becomes gradually smaller from the lower end portions to the upper end portions of the legs. A lens optical component includes a lens housing holding a lens, and the lens holder. The pair of leg members at the upper end portions are in contact with the lens housing, and welded at portions in contact with the lens housing. A package is equipped with the lens optical component and two or more optical components. The lens optical component is inserted in an optical path of the two or more optical components, and the height of the lens holder is set to be equal to a height of the input-output portion of an optical device.

    Abstract translation: 本发明提供一种透镜保持器，透镜光学部件或配备有透镜光学部件的封装，其中可能不会发生透镜壳体与透镜保持器之间的不良焊接。 透镜架包括从支撑构件倾斜并延伸到透镜壳体的一对腿构件，该支撑构件将透镜架支撑在预定位置。 一对腿部件之间的距离被设定为使得下端部之间的距离等于或大于待支撑的透镜壳​​体的宽度，并且上端部之间的距离等于或小于 透镜壳体被支撑，并且距离从腿部的下端部分到上端部逐渐变小。 透镜光学部件包括保持透镜的透镜壳体和透镜保持器。 上端部的一对腿部件与透镜壳体接触，并在与透镜壳体接触的部分处焊接。 包装配有透镜光学部件和两个或更多个光学部件。 将透镜光学部件插入到两个以上的光学部件的光路中，将透镜保持架的高度设定为与光学元件的输入输出部的高度相等。

    Abstract: PROBLEM TO BE SOLVED: To provide an optical connecting component in which stress given to optical fibers is relaxed, insertion loss, break of the optical fibers and polarized wave extinction ratio are improved and an array composing is easy. SOLUTION: The optical connecting component separates an inner space from outside with a housing (10), a lid (12) and a transmission window (600) provided on the housing. The transmission window is composed so that the optical fiber (200) or a planar light wave circuit (300) may be connected to the inner space side, a second optical fiber (202) or a second planar light wave circuit may be connected to the out part side, the light which propagates in the optical fiber or the planar light wave circuit may be connected to the second optical fiber or the second planar light wave circuit via the transmission window, or the light which propagates in the second optical fiber or the second planar light wave circuit may be connected to the optical fiber or the planar light wave circuit via the transmission window. The thickness of the transmission window is such that the coupling loss of light is within 0.5 dB, and the thermal expansion/contraction coefficient of the transmission window is smaller than the thermal expansion/contraction rate of the housing.
