A Bloch surface wave (BSW) sensor based on the hollow fiber (HF) inner coated with the one-dimensional photonic crystal (1DPC) consisting of TiO2 and SiO2 bilayers is proposed. It's the first time 1DPC is used in HF sensors. The proposed sensor has an ultra-high figure of merit (FOM), which is two orders of magnitude higher than that of the HF surface plasmon resonance (SPR) sensor. Moreover, the proposed sensor has a much broader practical RI detection range.

基于布洛赫表面波的超高品质因数一维光子晶体内涂层空心光纤传感器


提出了一种基于中空纤维（HF）内部涂覆由TiO2和SiO2双层组成的一维光子晶体（1DPC）的布洛赫表面波（BSW）传感器。这是 1DPC 首次用于 HF 传感器。该传感器具有超高品质因数（FOM），比高频表面等离子共振（SPR）传感器高两个数量级。此外，所提出的传感器具有更广泛的实际 RI 检测范围。
