最大纳米光子响应的光学材料

Optical Materials for Maximal Nanophotonic Response

Hyungki Shim, Zeyu Kuang, Owen D. Miller

摘要:

本文综述了能够实现最大光学响应的材料特性。我们强调的理论结果,使形状无关的量化材料的“品质因数”,从经典的总和规则,最近的单频散射界限。在光学频率上的一个关键分界线是支持高度亚波长共振的极化激元材料和可以具有非常小的损耗率的介电材料之间。我们讨论的关键指标,使这些材料类内和它们之间的比较。我们讨论了类似的二维材料的指标,并指出应用程序,可以进行严格的比较散装和二维材料的方法。各种结果突出了材料发现和理论纳米光子边界之间的协同作用,并指出在光-物质相互作用中实现新的极端的机会。

英文摘要:

This article reviews the material properties that enable maximum optical response. We highlight theoretical results that enable shape-independent quantification of material "figures of merit," ranging from classical sum rules to more recent single-frequency scattering bounds. A key delineation at optical frequencies is between polaritonic materials that support highly subwavelength resonances and dielectric materials that can have vanishingly small loss rates. We discuss the key metrics that enable comparisons both within these material classes and between them. We discuss analogous metrics for 2D materials, and point to applications for which rigorous comparison can be made between bulk- and 2D-material approaches. The various results highlight the synergy between materials discovery and theoretical nanophotonic bounds, and point to opportunities in achieving new extremes in light--matter interactions.
