Photonic Crystalline (PCF)-based SPR (Surface Plasmon Resonance) sensors continue to develop and achieve good performance, but in previous studies, PCF-SPR only has a small refractive index range detection, complex geometric structure, and low sensitivity. In this paper, we investigate the performance of the Star-shaped PCF-SPR sensor (S-PCF-SPR) in detecting the refractive index of the analyte. We performed numerical simulations using the finite element method (FEM) based on COMSOL Multiphysics version 5.6. It was found that S-PCF-SPR can detect analytes in a wide refractive index range from 1.3 to 139 RIU. S-PCF-SPR has a maximum wavelength sensitivity of 12000 nm/RIU, and the sensor resolution resulting from S-PCF-SPR 5.4 ×10 -5 . These results indicate that the S-PCF-SPR can be used as a sensor for sensitive analyte sensing applications and has good sensor resolution.
