论文摘要
尽管由于缺乏简单的形式主义而捕获了光学机械系统中的非热性，但由于耗散光学机电耦合而引起的几种新颖特征，但这种效果仍然充满探索。在这封信中，我们表明基于准模式的扰动理论能够正确预测分散和耗散的光力耦合。我们通过模拟以及与文献中报道的实验结果进行比较来验证我们的模型。最后，我们将这种形式主义应用于用于分子验光力学的等离激元系统，其中观察到振动模式的放大时强烈的耗散耦合特征。
Despite the several novel features arising from the dissipative optomechanical coupling, such effect remains vastly unexplored due to the lack of a simple formalism that captures non-Hermiticity in optomechanical systems. In this Letter, we show that quasinormal-mode-based perturbation theory is capable of correctly predicting both dispersive and dissipative optomechanical couplings. We validate our model through simulations and also by comparison with experimental results reported in the literature. Finally, we apply this formalism to plasmonic systems, used for molecular optomechanics, where strong dissipative coupling signatures in the amplification of vibrational modes are observed.
