    • PURPOSE:To decrease optical loss by constituting terminal parts of a material having the etching rate higher than the etching rate of an optical fiber, projecting the end faces of the optical fibers by an etching treatment slightly from the terminal parts and butting the end faces to each other. CONSTITUTION:The terminal part 2 is constituted of the material which is more easily etched than the optical fiber 1. The end face of the optical fiber 1 and the terminal part 2 are polished to a specular surface state and are formed flush with each other. The end part is dipped for specified time in an etching liquid 3, then the end of the terminal part 2 projects slightly from the end of the terminal part 2 and a projecting part 5 is formed. The length of the projection is adjusted by the dipping time in the etching liquid. A pair of the optical fibers 1 and the terminal parts 2 having such end shapes are butted to each other and a precision sleeve 4 is packaged thereto, by which an optical connector is constituted. The space between the fibers 1 is therefore eliminated, by which the optical loss by the Fresnel reflection is decreased and operability is improved. The long-term stability is thus assured.
    • 目的:通过构成蚀刻速率高于光纤蚀刻速率的材料的端子部分来减少光损耗,通过蚀刻处理稍稍从端子部分突出光纤的端面,并将端面对接到 彼此。 构成:端子部2由比光纤1更容易蚀刻的材料构成。光纤1的端面和端子部2被抛光成镜面状态,并且彼此平齐。 将端部在蚀刻液3中浸渍规定时间,然后端子部2的端部从端子部2的端部稍微突出,形成突出部5。 通过蚀刻液中的浸渍时间来调节投影的长度。 一对光纤1和具有这种端部形状的端子部件2彼此对接并且精密套筒4被封装在其中,由此构成光连接器。 因此纤维1之间的空间因此被消除,由此通过菲涅耳反射的光学损耗降低并且可操作性得到改善。 从而确保长期稳定。

    • PURPOSE:To form a nonreflective hard phi coat by inserting an optical fiber fixedly in the hole of a center part, and finishing one end optically to an optical coating treated surface and making other end side into an optical fiber connector. CONSTITUTION:A ferrule 2 constituting the optical fiber connector is cylindrical and an adaption hole 3 where the optical fiber 1 is inserted is formed at its center part; and the optical fiber 1 is inserted into the hole 3, which is charged with a heat-resistive adhesive 4 to fix the fiber. An end surface of the optical fiber 1 is almost aligned with one end 5 of the ferrule 2 and the other end side 6 projects by proper length. In this state, the end surface 5 is polished and finished selectively and optically into a recessed surface which is perpendicular to the optical axis or slants properly to a perpendicular surface. Further, an optical coating 7 such as a light-nonreflective coating, a transmission increasing coating, and a light wavelength selectable transmissive coating is vapor-deposited on the end surface 5. The coating 7 is vapor-deposited under sufficient conditions while the whole optical fiber 1 is stored in a vapor-depositing device because it is adequately long, so that the hard phi coat is formed.
    • 目的:通过将光纤固定在中心部分的孔中,将光纤固定在光学涂层处理表面上并将另一端侧制成光纤连接器,从而形成非反射硬质涂层。 构成:构成光纤连接器的套圈2为圆筒状,插入光纤1的适配孔3形成在其中央部; 并且将光纤1插入到孔3中,孔3中装有耐热粘合剂4以固定光纤。 光纤1的端面几乎与套圈2的一端5对准,另一端侧6突出适当的长度。 在这种状态下,端面5被选择性地和光学地抛光和精加工成垂直于光轴的凹入表面或者适当地倾斜到垂直的表面。 此外,在端面5上气相沉积诸如光非反射涂层,透射增加涂层和光波长可选透射涂层的光学涂层7,在充分条件下气相沉积涂层7,而整个光学 纤维1由于其充分长而储存在气相沉积装置中,从而形成硬质涂层。
