时域吸收异常点的激发

Excitation of absorbing exceptional points in the time domain

Asaf Farhi, Ahmed Mekawy, Andrea Alu, Douglas Stone

摘要:

我们分析的时域动力学的谐振器支持例外点(EP),在这两个本征频率和本征模式与输入波的完美捕获合并。我们发现EP的时域特征是可以完美捕获的波形类别的扩展。我们表明,这样的谐振器具有改善的性能,用于存储或转换能量。它们也可用于在该类中的波形之间进行转换。我们解析推导出这些功能,并证明他们耦合光学谐振腔系统的几个例子。

英文摘要:

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.
