Abstract
An apparatus includes a waveguide having a core layer and first and second cladding layers on opposite sides of the core layer, wherein the cladding layers comprise a binary oxide composition. In another example, the cladding layers include a ternary or quaternary combination of oxides and/or oxynitrides. In another example, the cladding layers include a silicon oxynitride.
