标题： Quality factors and dynamical tunneling in annular microcavities

摘要： 光学微腔中光学模式的关键特性是其品质因数，该因数描述了光学损耗。 这种量的数值计算对现代表面器件来说可能非常耗时。 在这里，我们展示了一类特定的耳语画廊腔体，其品质因数与动力学隧穿有关，这是量子混沌领域研究的现象。 我们将一种最近开发的动力学隧穿率确定方法扩展到开放腔体。 这使我们能够推导出一个品质因数的解析公式，该公式与麦克斯韦方程组的完整解非常吻合。 显示英文摘要

摘要： The key characteristic of an optical mode in a microcavity is its quality factor describing the optical losses. The numerical computation of this quantity can be very demanding for present-day devices. Here we show for a certain class of whispering-gallery cavities that the quality factor is related to dynamical tunneling, a phenomenon studied in the field of quantum chaos. We extend a recently developed approach for determining dynamical tunneling rates to open cavities. This allows us to derive an analytical formula for the quality factor which is in very good agreement with full solutions of Maxwell's equations.
