“…The refractive index of their environment greatly affects the performance of these SPWs. Thus, local SRIs may be readily recognized by monitoring amplitude, resonance wavelength, as well as spectral mode shifts [ 44 , 47 , 48 ].…”

“…Sensor performance is greatly affected by the fluctuation of the gold layer, as the metal layer generates surface plasmon waves. Due to damping effects, the depth of loss decreases as the gold layer thickness increases [ 48 ]. Loss depth & amplitude sensitivity for the difference in gold thickness at analytes RI 1.37 and 1.38 for x polarized mode are depicted in Fig.…”

“…The PCF structure has been correctly found to be sensitive for the temperature sensing purpose with detection range of 23 °C when the diameter d 3 is 0.20 μm. As for the pitch size to be 1 μm, the fabrication process can be done following the stack-and-draw method mentioned by MR Islam et al [ 48 ] where the optimized pitch size was also considered as 1 μm. Also, pitch size of 0.65 μm and air hole diameter of 0.11 μm has been fabricated adopting the stack-and-draw method by Wiederhecker et al [ 78 ].…”

Spurred by the rapid development of fiber optic sensing technology, photonic crystal fiber (PCF) sensors based on surface plasmon resonance (SPR) have received widespread attention. However, they can only detect a narrow range, and the coating process is complex. Herein, a wide-range SPR sensor is designed. It consists of a ring-core PCF filled with plasmonic materials. Compared to the process of depositing a coating inside the air hole, the analyte and gold nanowires fill our PCF, thus simplifying the manufacturing complexity. The ring-core structure enhances the directional power transmission between the guided mode and the surface plasmon polariton (SPP) mode. The sensor is numerically analyzed using the finite element method (FEM). The results show that the PCF-SPR sensor has a wavelength sensitivity and amplitude sensitivity of 40,000 nm/RIU and 2141 RIU−1, and the resolution is 2.5 × 10−6 RIU−1 for the detection range of 1.13–1.45. The high-sensitivity sensor boasting a wide refractive index detection range performs better than conventional solid-core PCF-SPR sensors, boding well for biochemical sensing.

“…SPR is a prominent analytical technique used in the investigation of interactivity between biomolecules, such as proteins, DNA, RNA [ 1 ], as well as interactions between molecules and surfaces. SPR relies on observing variances in the refractive index adjacent to the metal surface when molecules latch to it [ [2] , [3] , [4] , [5] ]. Surface Plasmon Resonance with Photonic Crystal Fibers innovatively leverages optical fibers with controlled air hole patterns for enhanced SPR capabilities [ 6 ].…”
