尽管迄今为止已经证明了奇异的材料特性，但多功能超材料的实际例子仍然非常罕见。元器件的概念是在混合超材料复合材料的背景下提出的：在该系统中，引入活性材料以提高可调谐性、可切换性和非线性。与在较低频率下观察到的成功杂交相反，由于缺乏具有非平凡活性的可用光学材料，以及难以以综合方式调节对外力的反应，对等离子体和光子纳米结构的探索有限。在这里，通过对电触发功能进行一系列概念验证研究，我们展示了二氧化钒集成光子超材料作为多功能控制的变革平台。所提出的与过渡材料集成的混合超材料代表了向前迈出的重要一步，它提供了一种通用的方法来创建自给自足和高度通用的纳米光子系统。 尽管有源超材料具有奇异的特性，但很少有报道，其中引入活性材料以提高可调谐性，可开关性和非线性。在这里，Liu等人展示了二氧化钒集成光子超材料作为多功能控制的变革平台。
Despite the exotic material properties that have been demonstrated to date, practical examples of versatile metamaterials remain exceedingly rare. The concept of metadevices has been proposed in the context of hybrid metamaterial composites: systems in which active materials are introduced to advance tunability, switchability and nonlinearity. In contrast to the successful hybridizations seen at lower frequencies, there has been limited exploration into plasmonic and photonic nanostructures due to the lack of available optical materials with non-trivial activity, together with difficulties in regulating responses to external forces in an integrated manner. Here, by presenting a series of proof-of-concept studies on electrically triggered functionalities, we demonstrate a vanadium dioxide integrated photonic metamaterial as a transformative platform for multifunctional control. The proposed hybrid metamaterial integrated with transition materials represents a major step forward by providing a universal approach to creating self-sufficient and highly versatile nanophotonic systems. Despite their exotic properties active metamaterials, where active materials are introduced to advance tunability, switchability and nonlinearity, are seldom reported. Here, Liu et al. demonstrate a vanadium dioxide integrated photonic metamaterial as a transformative platform for multifunctional control.
