This research introduces a biosensor utilizing surface plasmon resonance in photonic crystal fiber (PCF) configuration. PCF uses fused silica as the base material, with layer of gold placed over U-channels cross-section to create resonance. There are three different sizes internal optic air hole diameters, larger channel circle below u-channel for formation an energy leakage window. COMSOL software 6.0 assisted us tuning structure and performance study, structural parameters analyzed mainly include diameter, spacing, profundity measurement polished layer, nanoscale size variation metal films. The results simulation study show that optical sensor achieves refractive index (RI) responsiveness across 1.30 1.41 range, RI interval 1.40 1.41, exhibits largest peak shift, its highest sensitivity reaches 10,200 nm/RIU, smallest full width at half (FWHM) corresponds 1.34 value 4.8 nm, figure merit (FOM) 895.83 (1/RIU). software, was used simulate changes blood corresponding glucose concentrations, detection concentrations tested. Then, concentration 75 mg/dL–175 mg/dL is 3750 where maximum 5455 nm/RIU. It shows can be applied field biomedical applications, convenience, fast response, high sensitivity, it has great potential development prospect market.
