Abstract
Methods and materials are disclosed for providing an optical fiber transmission mixer wherein the cladding material is removed from an intermediate region of a plurality of fibers and the exposed fiber cores are encapsulated in a matching or slightly higher refractive index material. The encapsulated intermediate region of the fibers is then enclosed in a low index sheath to prevent light from escaping from the mixer.
