| dc.description.abstract | Over the years, various designs for traditional photonic crystal fibers (PCFs) and surface plasmon resonance photonic crystal fibers (SPR-PCFs) have been proposed, each demonstrating different structures, sensitivities, and confinement losses. Building on a comprehensive review of previous studies, we present a photonic crystal fiber biosensor based on surface plasmon resonance (SPR) with outstanding performance characteristics, designed using COMSOL Multiphysics 6.1. In this study, we developed a sensor incorporating air holes of varying diameters, strategically positioned to optimize performance. By meticulously fine-tuning all fiber parameters, we achieved a maximum amplitude sensitivity (AS) of 965.976 RIU−1 and a wavelength sensitivity (WS) of 134,000 nm/RIU, with a maximum sensor resolution of 4 × 10−4 RIU for the x-polarization. For the y-polarization, we attained a maximum amplitude sensitivity (AS) of 1167.53 RIU−1 and a wavelength sensitivity (WS) of 125,000 nm/RIU, with a maximum sensor resolution of 5 × 10−4 RIU. Additionally, the sensor achieved a maximum figure of merit (FOM) of 832.422 for the x-polarization and 1246.986 for the y-polarizatio. The maximum birefringence observed was 1.980 × 10−3. The overall analyte sensing range is from refractive indices 1.35 to 1.42, and the sensor has a fabrication tolerance limit of ±5%. With its enhanced performance in terms of sensitivity, we believe that this SPR-based PCF biosensor can potentially contribute to the detection of unknown analytes and play a significant role in medical diagnostics. | en_US |
