Abstract
Integrated optical waveguides and methods for the production thereof which have a patterned upper cladding with a defined opening to allow at least one side or at least one end of a light transmissive element to be air clad. The at least one side or at least one end is, for preference, a lens structure unitary with the waveguide, or a bend.
