摘要： An optical component as an embodiment of the present invention comprises an optical waveguide. This optical waveguide is a single optical waveguide having a first position and a second position along a longitudinal direction thereof. In this optical waveguide, cross-sectional refractive index profiles vary along the longitudinal direction between the first position and the second position. In this optical waveguide, at a predetermined wavelength to become a single mode at the first position, an overlap rate between a field distribution of light having propagated from the first position and having arrived at the second position, and a Gaussian distribution is not less than 90%.

摘要： The invention has an object to provide a method of making an optical fiber array in which bare fibers obtained by removing a coating of an optical fiber ribbon can be certainly arrayed on a V-groove substrate. A first feature of the invention is to use a positioning guide, and the positioning guide is provided with a recess portion having inclined wall surfaces, and its bottom portion is made to have a width equal to the whole width of the bare fibers in an arrayed state. By using this positioning guide, the optical fiber array can be made in a process as follows. In a state where bare fibers exposed by removing part of coating of tip portions of two fiber ribbons are alternately arranged, the positioning guide is raised from below. The bare fibers with irregular gaps are moved by the positioning guide and are arranged. In this state, the bare fibers are pressed by a fiber pressing member from above, and the V-groove substrate is raised, so that they are put on V grooves and are fixed by an adhesive.
摘要翻译：本发明的目的是提供一种制造光纤阵列的方法，其中通过去除光纤带的涂层而获得的裸露纤维可以可靠地排列在V形槽衬底上。本发明的第一个特征是使用定位引导件，并且定位引导件设置有具有倾斜壁面的凹部，并且其底部部分的宽度等于裸线纤维的整个宽度的排列州。通过使用该定位引导件，光纤阵列可以如下进行。在通过移除两个光纤带的末端部分的涂层的一部分而露出的裸露纤维线交替布置的状态下，定位引导件从下方升高。具有不规则间隙的裸露纤维通过定位引导件移动并被布置。在这种状态下，裸纤维被纤维挤压件从上方挤压，V形槽衬底被升高，使它们放在V形槽上并用粘合剂固定。

摘要： The present invention provides a fiber optic connector comprising a fiber pressing member and a substrate having a part A with multiple fiber arranging grooves in which bare portion of optical fibers are fixed, and a part B in which coated portion of optical fibers are fixed, and its manufacturing method. The connector enables to prevent an increase in transmission loss or breakage of the optical fibers by reducing the localized stress on the fibers from the rear end of the fiber pressing member and the rear end edge of the fiber arranging grooves.
