论文摘要
我们提出了一个独特的框架，以研究连续体（BIC）中光学结合状态的拓扑特性。我们采用了在特种光学微腔内进行避免共振交叉的接近性共振之间的相互作用。我们利用连续的系统参数调整来诱导消除泄漏损失的共振之间的破坏性干扰。与Friedrich-Wingten Type-BIC的物理见解相似，我们演示了超高质量模式的演变。我们报告了连接多个准BIC的位置的系统参数空间中特殊BIC线的形成。为了开发一种新的方案，以增强微腔中光学传感的性能，我们研究了传输系数和质量因子的敏感性，以感知系统配置中的超小扰动。
We propose a unique framework to study the topological properties of an optical bound state in the continuum(BIC). We employ the interactions between proximity resonances undergoing avoided resonance crossing in a specialty optical microcavity. We utilize a continuous system parameter tuning to induce destructive interference between the resonances with cancelling leakage losses. Similar to the physical insight of Friedrich-Wingten type-BIC, we demonstrate the evolution of an ultra-high quality mode. We report the formation of a special-BIC line in the system parameter space connecting locations of multiple quasi-BICs. Aiming to develop a novel scheme to enhance the performance of optical sensing in microcavity, we study the sensitivity of transmission coefficients and quality factor to sense even ultra-small perturbations in the system configuration.
