AI总结:

本文提出了一种综合模型,用于描述具有有效半径变化的圆柱微谐振器中电场的Kerr非线性动力学,并与辐射源耦合。该模型考虑了完整的方位色散以及辐射源对微谐振器中场的影响,耦合系数通过实验确定。该模型成为研究非线性效应、产生轴向-方位模式和光学频率梳的强大工具。通过优化光源耦合点,该模型实现了非线性阈值的两倍改进。

英文摘要:

We propose a comprehensive model describing the Kerr nonlinear dynamics of an electric field in a cylindrical microresonator with an effective radius variation, coupled to a radiation source. The proposed system of equations for coupled azimuthal modes takes into account full azimuthal dispersion as well as the influence of the radiation source on the field in the microresonator with the coupling coefficients determined experimentally. The model appears a powerful tool to study nonlinear effects, generation axial-azimuthal modes and optical frequency combs. We illustrate the power of the model with optimization of the coupling point of the light source, getting two order of magnitude improvement for the nonlinear threshold.
