摘要
A phase grating with a connecting layer is proposed for reflective splitter with high efficiency. A fused-silica layer and a metal slab are between the grating region and the substrate, which are different from the conventional grating directly etched in material. The grating parameters are optimized by numerical simulation, including the grating depth and connecting layer thickness. The reflective beam splitter can have merits of high efficiency and wideband property to some extent, especially for TE polarization.
