论文摘要
未来的技术是基于高性能光学通信，超快计算和紧凑的生物传感的技术，将依赖于基于纳米光子学的密集包装的可重构光学电路。多年以来，血浆被认为是纳米级光学元件的唯一可用平台，但是最近出现的新型MIE共振磁通型通过在高索引介电纳米粒子和结构中采用共鸣，为纳米级光学元件提供了更实际的替代方案。在这个小评论中，我们强调了具有高质量因子（Q因子）的介电MIE谐振纳米结构物理学的一些最新趋势，可通过采用多极共振和连续体中的多极谐振和绑定状态，从而有效地对光的空间和时间控制光。我们讨论了这些概念在非线性光学，纳米层，次波长波引物和感应中的一些应用。
Future technologies underpinning high-performance optical communications, ultrafast computations and compact biosensing will rely on densely packed reconfigurable optical circuitry based on nanophotonics. For many years, plasmonics was considered as the only available platform for nanoscale optics, but the recently emerged novel field of Mie resonant metaphotonics provides more practical alternatives for nanoscale optics by employing resonances in high-index dielectric nanoparticles and structures. In this mini-review we highlight some recent trends in the physics of dielectric Mie-resonant nanostructures with high quality factor (Q factor) for efficient spatial and temporal control of light by employing multipolar resonances and the bound states in the continuum. We discuss a few applications of these concepts to nonlinear optics, nanolasers, subwavelength waveguiding, and sensing.
