摘要

在这项研究中，我们证明了可以通过控制胆甾液晶反射光获得的Pancharatnam-Berry (PB)相位来设计具有不同f数和焦距的平面反射微透镜，并使用等离子体光图技术制作出高质量的微透镜。我们测量了这些微透镜的点扩展函数，并表明它们是衍射受限的。这种方法制造平面微光学器件的一个优点是，它允许同时设计衍射限制质量和低制造成本。

Diffraction-Limited Flat Reflective Microlenses by Plasmonic Photopatterning of Molecular Orientations

In this study, we demonstrate that flat reflective microlenses with different f -numbers and focal lengths can be designed by manipulating the Pancharatnam–Berry (PB) phase obtained by light upon reflection from cholesteric liquid crystals and fabricated with high quality using a plasmonic photopatterning technique. We have measured the point-spread functions of these microlenses and show that they are diffraction-limited. An advantage of this approach for fabricating flat micro-optical devices is that it allows for the simultaneous design of diffraction-limited quality and low fabrication cost.
