Surface plasmon resonance (SPR) sensing methods enable highly sensitive, fast response, and label-free analysis of biomolecular interactions. For SPR sensors, sensitivity and full width at half maximum (FWHM) are two incompatible performance parameters. We propose a refractive index (RI) sensor using a dual-core photonic crystal ber (PCF) and SPR effects to achieve high sensitivity and narrow FWHM simultaneously. The air holes of the sensor appear in a hexagonal arrangement, and polishing technology introduces two polishing planes into the cladding. A gold lm is deposited on one side of the polished plane to form a highly sensitive RI sensing channel. Five gold nanowires are deposited on the other side of the polished plane to form a RI sensing channel with a narrow FWHM. We analyzed and optimized its structural parameters using the nite element method and determined the optimal structural parameters.The numerical results demonstrate that the maximum sensitivity of the sensor is 21000 nm/RIU, and a narrowest FWHM of 31 nm. Therefore, measuring the refractive index simultaneously with two sensing channels increases the detection accuracy of the measurement. In addition, the ndings further indicate that variations in structural parameters do not signi cantly impact the sensing performance of the senor, which makes the production of the sensor relatively simple. In conclusion, our work provides a new research method for realizing high sensitivity and narrow FWHM simultaneously.

Lossy mode resonance (LMR) sensors have garnered widespread attention in recent years. This work proposes a quasi-D-shaped eccentric core photonic quasi-crystal fiber LMR (PQF-LMR) sensor with an M-type perovskite coating surface. The sensor is based on a ten-fold Penrose PQF structure, featuring four kinds of air holes and perovskite coating deposited on the micro-groove surface. The sensing characteristics are analyzed using the finite element method. The results indicate that multiple LMRs can be excited in both Y-polarization and X-polarization. The 2 nd and 3 rd lossy modes exhibit outstanding performance in terms of sensitivity and figure of merit (FOM). The 2 nd lossy mode achieves a maximum sensitivity of 84,985 nm/RIU and an average sensitivity of 46,358 nm/RIU. In the 3 rd lossy mode, the maximum FOM reaches 904.34 RIU−1. For comparison, the quasi-D-shaped PQF-LMR sensor with a flat surface is also investigated. The PQF-LMR sensor with perovskite coating demonstrates superior sensing performance and significantly broadens the prospects for LMR sensors in various fields.
