Abstract

Achromatic retarders with a wide field of view (FOV) can maintain a consistent performance across a broad range of wavelengths and wide viewing angles. Despite the widespread use of retarders, achieving a true achromatic retarder with a wide FOV remains challenging. Here, we present an achromatic quarter-wave plate (QWP) based on form birefringence (FB) of nanostructures operating in visible wavelengths from 450 to 650 nm. Our 1.8-

μ

m-thick QWP was fabricated using a templated growth method that combines laser interference lithography and hydrothermal growth methods. A flat reflectance spectrum with an average reflectance of 1.37% was measured from the antireflection of a circular polarizer with the FB retarder, confirming the wideband efficiency of the QWP. The achromaticity of retardation was unchanged at greater incident angles.

利用模板生长ZnO纳米结构形成双折射的程序化消色差和宽视场缓速器

具有宽视场（FOV）的消色差缓速器可以在宽波长范围和宽视角范围内保持一致的性能。尽管缓速器的广泛使用，实现一个真正的消色差缓速器与宽视场仍然具有挑战性。在这里，我们提出了一种基于形式双折射（FB）的纳米结构的消色差四分之一波片（QWP），其工作波长为450至650 nm。采用激光干涉光刻和水热生长相结合的模板生长方法制备了1.8 μm厚的QWP。通过对带FB缓速器的圆偏振器的抗反射测试，得到了平均反射率为1.37%的平坦反射光谱，证实了QWP的宽带效率。在较大的入射角下，延迟的消色度不变。
