摘要

在本文中，我们开发了一种新型的光子筛，它由大量精确定位的孔组成，这些孔按照菲涅耳带板(FZP)的几何形状分布，而FZP的透明和不透明圆形环上的孔具有π相移。与我们称为振幅光子筛(PS)的传统光子筛相比，二元光子筛的透射率是振幅光子筛的两倍，衍射效率大约是振幅光子筛的四倍。制作了一个直径70毫米，f/10的二元光子筛，用于可见光下的工作。介绍了二元光子筛的设计、制造和性能。

Novel diffractive optical element: binary photon sieve

In this paper, we developed a novel photon sieve consisting of a large number of precisely positioned holes distributed according to an underlying Fresnel zone plate (FZP) geometry, while the holes at transparent and opaque circular rings of the FZP have a π phase shift. Compared to a conventional photon sieve which we call an amplitude-photon sieve (PS), the binary photon sieve has a transmission two times more amplitude-PS and a diffractive efficiency approximately four times than amplitude-PS. A 70-mm diameter, f/10 binary photon sieve has been fabricated for operation at visible light. Details of design, fabrication, and performance of the binary photon sieve are presented.
