ABSTRACT:
An optical circuit device has a carbon optical waveguide structure which has a substrate. A first carbon layer is atop the substrate and has a first refractive index. A carbon optical waveguide core is positioned atop the first layer and has a second refractive index different than the first refractive index. A cladding layer of carbon is positioned atop the first layer and the waveguide core and has a third refractive index different than the refractive index of the waveguide core.
