Abstract

We propose a D-shaped optical fiber sensor with the perovskite coating excited by lossy mode resonance (LMR). MAPbI₃ is a promising candidate for perovskite fiber sensors. LMRs produced by MAPbI₃ coating are demonstrated by the transmission spectra in the near infrared wavelength. The sensor can detect a wide range of surrounding refractive indices from 1 to 1.448, and the loss spectra of Y-polarization and X-polarization modes can be clearly distinguished. The position of the resonance peak can be adjusted by varying the film thickness to regulate the detection range and improve detection accuracy. The resonance width is reduced by adjusting the residual cladding thickness due to the light coupling at LMRs transmitted through the D-shaped optical fiber core to the perovskite coating. The maximum sensitivity reaches up to 35,000 nm/RIU and the maximum figure of merit is 925.68 RIU⁻¹ in the perovskite fiber sensor. Compared with D-shaped optical fiber sensors with conventional materials, the proposed sensor with perovskite coating shows superior sensing performance. Perovskite-based LMR sensing is a productive way to contribute to resonance optical fiber sensing technology and may make a breakthrough in the development of miniaturization, high detection accuracy and multi-target detection.

基于钙钛矿涂层d型光纤的高灵敏度有损模式谐振传感器

提出了一种损耗模共振激发钙钛矿涂层的d型光纤传感器。MAPbI3是一种很有前途的钙钛矿光纤传感器候选材料。MAPbI3涂层制备的LMRs在近红外波段的透射光谱得到了验证。该传感器可以检测到1 ~ 1.448范围内的周围折射率，y偏振模式和x偏振模式的损耗谱可以清晰区分。通过改变薄膜厚度，可以调节共振峰的位置，从而调节检测范围，提高检测精度。由于lmr处的光耦合通过d型光纤芯传输到钙钛矿涂层，通过调整残余包层厚度可以减小共振宽度。该钙钛矿光纤传感器的最大灵敏度可达35000 nm/RIU，最大优值为925.68 RIU−1。与传统材料的d型光纤传感器相比，采用钙钛矿涂层的传感器具有更好的传感性能。基于钙钛矿的LMR传感是为谐振光纤传感技术做出贡献的有效途径，可能在小型化、高检测精度和多目标检测方面取得突破。

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
