    摘要： To make an optical switch smaller, two frames are formed by etching in such manner that when they are stuck together to form a support member, an hexagonal opening appears. The end portions of a pair of fixed optical fibers are arranged in the bottom portions of a pair of opposing V-grooves provided in this hexagonal opening. A pair of movable optical fibers are fixed at the other end of the support member, and these movable optical fibers are arranged in such manner that their end faces are contiguous with the end faces of the pair of fixed optical fibers. A drive mechanism causes the end portions of this pair of vertically arranged movable optical fibers to move to the left or the right, come into contact with the walls of respective V-grooves, slide into the bottoms of the grooves, and thereby have their cores aligned with the cores of the fixed optical fibers. Alternatively, two parallel beams formed from silicon are formed on the inside of a single frame, a pair of mutually opposing projections are formed in approximately the middle portions of these beams, and the end portions of a pair of optical fibers are arranged in and in contact with V-grooves formed parallel to and on the opposing faces of this pair of projections.

    摘要翻译： 为了使光学开关更小，通过蚀刻形成两个框架，使得当它们被粘合在一起以形成支撑构件时，出现六边形开口。 一对固定光纤的端部布置在设置在该六边形开口中的一对相对V形槽的底部。 一对可动光纤固定在支撑构件的另一端，这些可动光纤以这样的方式配置，使得它们的端面与一对固定光纤的端面相邻。 驱动机构使这对垂直设置的可动光纤的端部向左或向右移动，与各个V形槽的壁接触，滑入槽的底部，从而具有它们的芯 与固定光纤的芯对准。 或者，在单个框架的内侧形成由硅形成的两个平行光束，在这些光束的大致中间部分形成有一对相互相对的突起，并且一对光纤的端部布置在 与平行于该对突起的相对面上的V形槽接触。
