Abstract
Methods for forming optical systems are provided. A representative method includes the steps of: providing a substrate; depositing on the substrate a first contoured channel preform of material capable of ion exchange with the substrate; and diffusing ions from the first channel preform into the substrate to form a first waveguide channel at least partially buried in the substrate. Optical systems and other methods also are provided.
Claims11
An optical system comprising:
- a substrate;
- a channel preform comprising a material operable to provide electrolytic ion exchange with said substrate, said channel preform exhibiting a change in cross-sectional area along at least a portion of a length of said channel preform;
- and
- a waveguide channel comprising ions that are diffused by electrolysis from said channel preform into said substrate, wherein at least a portion of said waveguide channel is at least partially buried in said substrate, said waveguide channel exhibiting a change in cross-sectional area along at least a portion of a length of said waveguide channel substantially the same as the change in cross-sectional area of said channel preform.
