论文摘要
我们介绍了一项关于光学系统的理论研究，其中机械谐振器调节了光腔的谐振频率（配色耦合）和衰减速率（耗散耦合）。我们将通用分散框架扩展到更通用的情况，在这种情况下，耗散耦合在其外部和内在贡献之间分配。我们报告了每种光损失（内在和外部）对三种耦合机制的影响的完整分析，并突出了每个外部衰减率制度的利益。提出了实验识别三个耦合及其对光学响应的相对影响的基本工具。我们证明了光弹簧效应和光力阻尼的一般表达。来自文献的光子晶体系统中的实验测量和我们的理论模态的比较得出了良好的一致性。
We present a theoretical study of optomechanical systems in which the mechanical resonator modulates both the resonant frequency (dispersive coupling) and the decay rates (dissipative coupling) of the optical cavity. We extend the generic dispersive framework to a more general case in which the dissipative coupling is split between its external and intrinsic contribution. We report a complete analysis of the influence of each kind of optical losses (intrinsic and external) on the three coupling mechanisms and highlight the interest of each external decay rate regime. The basic tools to experimentally identify the three couplings and their relative influence on the optical response are presented. We demonstrate the general expression of the optical spring effect and optomechanical damping. Comparison between experimental measurements in photonic crystal systems from the literature and our theoretical modal yields good agreement.
