ABSTRACT:
An optical waveguide fiber or body having a doped outer region which can be utilized in an optical coupler, a preform which can serve as the precursor for the fiber, an optical coupler, and methods of making same. Water, for example in the form of H2O and/or D2O, may be added to the cladding of the optical waveguide fiber or body.
