Abstract
Systems and methods of forming an optical coupling between two optical waveguides where at least one of the optical waveguides is non-UV transmissive are disclosed. In one aspect, a self-forming waveguide (SFWG) is formed in a photosensitive material disposed between a UV transmissive optical waveguide and a non-UV transmissive component at least in part by a portion of an incident UV beam reflected from an interface between the photosensitive material and the non-UV transmissive material. In another aspect, two separate SFWG waveguides are formed in two separate photosensitive materials by UV beams passed thereto via a UV transmissive bridge waveguide.
