论文摘要
我们分析了支持特殊点（EPS）的谐振器的时域动力学，在该动力学方面，本征频和与输入波融合的完美捕获相关的特征频率和特征模式。我们发现，EP的时间域签名是可以完美捕获的波形类别的扩展。我们表明，此类共振器在存储或转导能量方面的性能提高了。它们还可以用于在此类中的波形之间转换。我们通过分析得出这些特征，并为它们演示了几个耦合光谐振系统的示例。
We analyze the time-domain dynamics of resonators supporting exceptional points (EPs), at which both the eigenfrequencies and the eigenmodes associated with perfect capture of an input wave coalesce. We find that a time-domain signature of the EP is an expansion of the class of waveforms which can be perfectly captured. We show that such resonators have improved performance for storage or transduction of energy. They also can be used to convert between waveforms within this class. We analytically derive these features and demonstrate them for several examples of coupled optical resonator systems.
