Abstract
An optical fiber junction device for coupling a pair of optical fibers with a third optical fiber. A portion of the cladding is etched from the end portions of the pair of fibers, and those end portions are then secured together in side-by-side relationship so that their endfaces are coplanar. The third fiber is so disposed that the end portion thereof is substantially parallel to the end portions of the pair of fibers, and its endface is adjacent to the endfaces of the pair of fibers. Means is provided for causing lateral movement between the endfaces of the pair of fibers and that of the third fiber to vary the amount of light coupled between the pair of fibers and the third fiber.
