由具有高或中等折射率的介电材料制成的纳米结构可以在光学区域支持强烈的电磁共振。因此，它们可以作为纳米谐振器发挥作用。除了已被广泛研究的等离子体金属纳米结构外，介电纳米谐振器还为实现强大而通用的纳米级光操纵提供了一种新型的构建块。与等离子体金属纳米结构相比，由合适的介电材料制成的纳米谐振器成本低，地球资源丰富，光能损失非常小，甚至可以忽略不计。因此，它们将在许多光子器件中找到潜在的应用，特别是那些需要低能量损耗的器件。本文综述了介电纳米谐振器的实验和理论研究的最新进展。我们从介电纳米谐振器电磁响应的基本理论及其制备方法入手。然后阐述了单个介电纳米谐振器的光学性质，以及介电纳米谐振器之间、介电纳米谐振器与衬底之间以及介电纳米谐振器与等离子体金属纳米结构之间的耦合行为。进一步描述了介电纳米谐振器的应用。最后，讨论了该领域面临的挑战和机遇。
Nanostructures made of dielectric materials with high or moderate refractive indexes can support strong electric and magnetic resonances in the optical region. They can therefore function as nanoresonators. In addition to plasmonic metal nanostructures that have been widely investigated, dielectric nanoresonators provide a new type of building blocks for realizing powerful and versatile nanoscale light manipulation. In contrast to plasmonic metal nanostructures, nanoresonators made of appropriate dielectric materials are low-cost, earth-abundant and have very small or even negligible light energy losses. As a result, they will find potential applications in a number of photonic devices, especially those that require low energy losses. In this review, we describe the recent progress on the experimental and theoretical studies of dielectric nanoresonators. We start from the basic theory of the electromagnetic responses of dielectric nanoresonators and their fabrication methods. The optical properties of individual dielectric nanoresonators are then elaborated, followed by the coupling behaviors between dielectric nanoresonators, between dielectric nanoresonators and substrates, and between dielectric nanoresonators and plasmonic metal nanostructures. The applications of dielectric nanoresonators are further described. Finally, the challenges and opportunities in this field are discussed.
