The reported "trapped rainbow" storage of THz light in metamaterials and plasmonic graded structures has opened an attractive new method to control electromagnetic radiation. Here, we show how, by incorporating the frequency-dependent dielectric properties of the metal, the graded grating structures developed for "trapped rainbow" storage of THz light in mum level can be scaled to nm level for telecommunication waves for applications in optical communication and various nanophotonic circuits.
据报道，太赫兹光在超材料和等离子体渐变结构中的“捕获彩虹”存储开启了一种控制电磁辐射的新方法。在此，我们展示了如何通过结合金属的频率相关介电特性，将为太赫兹光在微米级的“捕获彩虹”存储而开发的渐变光栅结构缩小到纳米级，以用于电信波，应用于光通信和各种纳米光子电路。
