Abstract
Various embodiments provide a waveguide with reduced optical power loss. The waveguide comprises a waveguide core having a core index of refraction; and a cladding disposed about at least a portion of a perimeter of the waveguide core. The cladding includes a plurality of layers that define a periodic index of refraction. The plurality of layers includes a core-adjacent layer having a core-adjacent layer index of refraction. The core index of refraction is greater than the core-adjacent layer index of refraction.
