Abstract
The present invention provides a waveguide, a method of manufacture therefore, and an optical communications system including an optical device comprising the waveguide. The waveguide may comprise a substrate, a planar waveguide core located over the substrate and a cladding layer located adjacent the planar waveguide core, the cladding layer comprising a silsesquioxane oligomer.
Claims23
