Paper Abstract

Recent experimental and numerical results clearly evidence that blazed-binary diffractive elements outperform their standard blazed-echelette counterparts in the resonance domain. A theoretical study of 1D blazed-binary gratings shows that the reason for this high efficiency is a waveguiding effect in the subwavelength features. The outcome is a reduction of the shadowing zone.
