调谐泄漏纳米腔共振-微扰处理
Tuning Leaky Nanocavity Resonances - Perturbation Treatment
摘要：
有限寿命纳米腔电磁模式的绝热频率调谐也影响它们的品质因数（Q）。由（实）频率调谐引起的微扰Q变化是一个可控参数。在这里，介电常数调制（DCM）对腔谐振的影响，通过一阶微扰分析的三维腔辐射损耗。推导了DCM引起的腔模频率和Q值变化的半解析表达式。所得结果与数值计算结果吻合较好。
英文摘要：
Adiabatic frequency tuning of finite-lifetime-nanocavity electromagnetic modes affects also their quality-factor (Q). Perturbative Q change resulting from (real) frequency tuning, is a controllable parameter. Here, the influence of dielectric constant modulation (DCM) on cavity resonances is presented, by first order perturbation analysis for a 3D cavity with radiation losses. Semi-analytical expressions for DCM induced cavity mode frequency and Q changes are derived. The obtained results are in good agreement with numerical calculations.
