A recent experiment by Kwak et al. [Sci. Rep. 5, 9010 (2015)10.1038/srep09010] demonstrated the relevance of resonance-assisted tunneling for optical microcavities where resonance chains emerge in phase space due to boundary deformations. In this paper we adapt the perturbative description of resonance-assisted tunneling to calculate optical modes and the imaginary part of their complex wavenumber which determines the lifetime of the mode. We demonstrate our method at three example cavity shapes and compare our results to numerical data and perturbation theory for weakly deformed microdisk cavities.
夸克等人[《科学报告》5, 9010 (2015)10.1038/srep09010]最近进行的一项实验表明，对于光学微腔而言，共振辅助隧穿具有重要意义，在这种微腔中，由于边界变形，共振链在相空间中出现。在本文中，我们采用共振辅助隧穿的微扰描述来计算光学模式及其复波数的虚部，该虚部决定了模式的寿命。我们在三种示例腔形状上展示了我们的方法，并将我们的结果与弱变形微盘腔的数值数据和微扰理论进行了比较。
