Abstract
A multilayer optic device having an input face and an output face is provided. The optic device includes a high-index material layer having a first real refractive index 1−δand a first absorption coefficient β, wherein the core comprises a first surface and a second surface, a low-index material layer having a second real refractive index 1−δand a second absorption coefficient β, and a grading zone disposed between the high-index material layer and low-index material layer, the grading zone comprising a grading layer having a third real refractive index 1−δand a third absorption coefficient β, such that 1−δ1>1−δ>1−δ, where at least a portion of one or more of the high-index material layer, the grading zone and the low-index layer comprises one or more corrugations along a first direction.
