论文摘要
在一系列能量和传感应用中，控制热发射器的光谱响应变得越来越重要。在光子系统中实现任意频谱选择性的常规方法已需要将多个共振元素结合在一起，以通过数值优化实现一系列光谱曲线，并且缺乏通用的理论框架。在这里，我们开发了一种时间耦合模式理论，用于从多个静电耦合的谐振器中进行热发射。我们验证了我们的理论对复杂的二维纳米光热发射器的数值模拟，突出了异常的热发射光谱，当具有任意特性的多个谐振器彼此之间彼此之间具有不同强度的彼此彼此时，它们可能会出现。
Controlling the spectral response of thermal emitters has become increasingly important for a range of energy and sensing applications. Conventional approaches to achieving arbitrary spectrum selectivity in photonic systems have entailed combining multiple resonantly emissive elements together to achieve a range of spectral profiles through numerical optimization, with a universal theoretical framework lacking. Here, we develop a temporal coupled mode theory for thermal emission from multiple, arbtirarily-coupled resonators. We validate our theory against numerical simulations of complex two- and three-dimensional nanophotonic thermal emitters, highlighting the anomalous thermal emission spectra that can emerge when multiple resonators with arbitrary properties couple to each other with varying strengths.
