Abstract
Waveguides that include a top cladding layer; a bottom cladding layer; and a core layer positioned between the top cladding layer and the bottom cladding layer, the core layer including a material having a refractive index of not less than 2.1, for example amorphous hydrogenated silicon carbide (SiC:H), or bismuth titanate. Methods of forming core layers of waveguides are also disclosed.
