ABSTRACT:
This invention relates to a method of making fiber optic interferometers. First, a plurality of optical fibers are bundled and placed into a sleeve. The bundle is then encased in the sleeve and the fiber ends are cut and polished. An area of cladding is stripped back from the polished fiber ends and layers of material are deposited on the fiber ends. These layers of material have varying indexes of refraction and form a grating. The bundle of optical fibers is then removed from encasing in the sleeve.
