我们发现，具有双曲色散的超材料支持大量的电磁状态，可以耦合到量子发射器，导致宽带珀塞尔效应。所提出的辐射衰变工程方法，可用于单光子源，荧光成像，生物传感和单分子检测等应用，也开辟了使用双曲超材料探测原子和人造原子（如量子点）的自发辐射特性的可能性。(C)2012年美国物理学会。[http：//dx.doi.org/10.1063/1.4710548]
We show that metamaterials with hyperbolic dispersion support a large number of electromagnetic states that can couple to quantum emitters leading to a broadband Purcell effect. The proposed approach of radiative decay engineering, useful for applications such as single photon sources, fluorescence imaging, biosensing, and single molecule detection, also opens up the possibility of using hyperbolic metamaterials to probe the spontaneous emission properties of atoms and artificial atoms such as quantum dots.
