ABSTRACT:
An adjustable coupling device for fiber-optic power dividers in which the coupling characteristics of the divider are influenced by application of transverse forces on the optic fibers in a repeatable fashion. The preferred embodiment consists of a pair of optical fibers which are evanescently coupled by having a portion of each etched to a core and twisted about the other. The etched and twisted portions of these fibers are encased in a rigid housing filled with an elastic filler material. Means are provided for creating forces in the filler material which are transverse to the fibers.
