ABSTRACT:
A variable width waveguide useful for mode matching between dissimilar optical waveguides and optical fibers and a method for making the same is described. In one embodiment, a tapered waveguide is etched in a substrate, a cladding material is laid over the upper surface of the substrate and within the waveguide, and the waveguide is then filled with a core material. The core material may be deposited in a single step, or in successive deposition steps.
