论文摘要
我们考虑使用介电光栅中连续体（BICS）中的光界面状态折射率传感。采用扰动方法，我们得出了在BIC的光谱附近运行的传感器的差异灵敏度和功绩。提出了用于工程的优化设计方法。得出了具有光学BIC的最大灵敏度的分析公式。 结果提供了直接的数值模拟。
We consider refractive index sensing with optical bounds states in the continuum (BICs) in dielectric gratings. Applying a perturbative approach we derived the differential sensitivity and the figure of merit of a sensor operating in the spectral vicinity of a BIC. Optimisation design approach for engineering an effective sensor is proposed. An analytic formula for the maximal sensitivity with an optical BIC is derived. The results are supplied with straightforward numerical simulations.
