Abstract

Embodiments described herein relate to augmented waveguide regions. The augmented waveguide regions generally include pluralities of gratings having duty cycles and refractive indices. In certain embodiments, the duty cycles are different, the refractive indices are different, or both the duty cycles and the refractive indices are different. Also described herein are methods for forming the augmented waveguide regions.
