The modulation of the electric field intensity distribution within the PCF is achieved by filling specific air holes with auxiliary liquid, leading to improved properties of the PCF-LSPR sensor. Moreover, the detection range of the sensor can be tailored by adjusting the RI of the auxiliary liquid. Using the full-vector finite element method (FEM), simulations of sensor performance are conducted. Results demonstrate that with an auxiliary liquid RI of 1.41, the sensor achieves a maximum RI sensitivity of 52438.02 nm/RIU and a detection range of 1.27–1.41. Similarly, with an auxiliary liquid RI of 1.43, the sensor achieves a maximum RI sensitivity of 46611.18 nm/RIU and maintains a detection range of 1.23–1.41. This approach allows for customization without altering the sensor geometry, facilitating the adjustment of the auxiliary liquid RI based on specific sensing requirements.
