    • A plasmonic optical spectrum filtering device is provided that filters electromagnetic waves by optical resonance, for example, by selective conversion between the free-space waves and spatially confined modes in plasmonic nano-resonators. Frequency-selective transmission and reflection spectra are engineered and can be used as spectrum filters for display and imaging applications. A thin film stack color filter is further disclosed, which can be designed to either function as a transmission color filter with efficiency twice that of conventional colorant based color filter; or as a reflective color filter for display devices (e.g., used in an energy harvesting reflective display). In other variations, a novel reflective colored display is viewable under direct sunlight, and can simultaneously harvest both incident light and generate electrical power. Methods of making such plamonic optical spectrum filtering devices are also provided.
    • 提供了等离子体激发光谱滤波装置,其通过光谐振来对电磁波进行滤波,例如通过在等离子体激元纳米谐振器中的自由空间波和空间限制模式之间的选择性转换。 频率选择性传输和反射光谱被设计并且可以用作用于显示和成像应用的频谱滤波器。 进一步公开了一种薄膜堆叠滤色器,其可以被设计成作为传统滤色器的功能,效率是传统的基于着色剂的滤色器的两倍; 或用作显示设备的反射滤色器(例如,用于能量收集反射显示器)。 在其他变型中,新颖的反射彩色显示器可在直射的阳光下观看,并且可以同时收集入射光并产生电力。 还提供了制造这种同谱光谱滤波装置的方法。
