提出了一种包含金属介电亚波长光栅的多层结构，该结构具有可见光偏振分离的特性，能够产生反射共振和独特的偏振相关颜色效应。讨论了其在TE和TM极化下的反射共振和颜色，以及其结构参数对它们的影响。设计制作了te偏振光为红色、tm偏振光为绿色、日光为黄色的反射滤光片，将其光栅区域替换为正弦光栅，并对其相关特性进行了验证。该结构及其特性可以在色彩安全、图像再现、色彩过滤、基于偏振的信息隐藏等各个领域实现实际应用。(C) 2011美国光学学会
A multilayered structure incorporating a metal-dielectric subwavelength grating, with the characteristic of polarization separation for visible light and the capability of creating reflection resonance and distinctive polarizationdependent color effects, is proposed. Its reflection resonance and color for TE and TM polarizations are discussed, as well as the influence of its structural parameters on them. Moreover, a reflection filter with characteristics of red for TE-polarized light, green for TM-polarized light, and yellow for daylight is designed and fabricated by replacing its grating region with a sinusoidal grating, and its related characteristics also are verified. The structure and its properties can achieve practical applications in various fields, such as color security, image reproduction, color filtering, and polarization-based information hiding.
