Semi-analytical design of antireflection gratings for photonic crystals
arXiv:1108.2173 · doi:10.1103/PhysRevB.85.035114
Abstract
This article concerns the design of antireflection structures which, placed on a photonic crystal surface, significantly diminish the fraction of energy lost to reflected waves. After a review of the classes of these structures proposed to date, a new method is presented in detail for the design of antireflection gratings operating in a wide range of angles of incidence. The proposed algorithm is illustrated by means of several examples, showing the advantages and limitations.
