Abstract: A device, or a pixel of a device, for filtering of incident radiation includes an array of discrete micro-resonant elements in an encapsulated layer, the encapsulating material having a lower index of refraction than the micro-resonant elements. A highly reflective filtering structure is positioned a first distance above the encapsulated layer and/or a second distance below the encapsulated layer, and is characterized by a stopband. The array of discrete micro-resonant elements is configured to transmit a passband of incident radiation centered around a center wavelength that falls within the stopband of the highly reflective filtering structure, and to minimize a dependence of the center wavelength on an angle of incidence (Aol) of the incident radiation. A pixelated device includes a plurality of pixels, each having an array of the discrete micro-resonant elements tuned to transmit a different passband having a different center wavelength, while minimizing dependence on Aol.

Abstract: 一种亚波长光栅光学膜，包括多个并排重复设置的一维周期光栅单元，每个周期为p的光栅单元包括第一介质(1)、第二介质(2)、第三材料(3)、第四材料(4)、第五材料(5)、第六介质(6)和第七介质(7)，在并排周期设置的多个光栅单元的底部设置作为衬底的第六介质(6)、顶部设置作为覆盖层的第七介质(7)。通过控制光栅周期和折射率，使得入射蓝紫光满足在最高折射率层内的衍射角度小于90度；通过调整光栅的占空比和各层材料厚度，使得蓝紫光波段的透射光能量最低，从而可以隔绝有害蓝紫光，这种方法比传统镀膜方式成本更低。

Abstract: As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color. The article includes the optical element on its surface and the optical element includes one or more layers (e.g., a reflective layer(s), a constituent layer(s), and the like). The optical element can include a plurality of different sections, where each of the different sections have a different relative thickness.

Abstract: As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color. The article includes the optical element (e.g., a single layer reflector, a single layer filter, a multilayer reflector or a multilayer filter) including one or more layers (e.g., a reflective layer(s), a constituent layer(s), and the like). The surface of the article can include the optical element with regions that impart different structural colors. The different structural colors imparted are due at least in part to the different structure (e.g., cross-sectional structure) of the optical element in certain regions.
