Abstract
A mechanism for achieving symmetrical stress loads on operating optical fibers () held in fiber optic arrays includes, in one embodiment, the provision of a pair of non-operating or dummy fibers(), each located outboard of the outermost or curb fibers(″) of the array. All of the fibers, whether operating or dummy, are held in corresponding grooves () in a substrate (). A cover plate () may be positioned thereover while a low stress glue or potting compound () is introduced or applied so as to completely encapsulate the fibers. The glue or potting compound will symmetrically surround all of the operating fibers whereby not only any inboard operating fibers ('), but also the outboard operating curb fibers (″), are symmetrically encapsulated. In this manner all of the operating fibers are subject to the same stresses and consequently will exhibit essentially the same polarization maintaining behavior. The invention is primarily beneficial with polarization-maintaining optical fibers, but will work effectively with other types of optical fibers as well, wherever stress are a concern.
