title = "Circular Split Cores Based Highly Sensitive Photonic Crystal Fiber Refractive Index Sensor",
abstract = "This paper supports the progress of refractive index (RI) sensor using two cores of photonic crystal fiber (PCF) with liquid infiltration. The PCF{\textquoteright}s centre circular air hole divides the two fiber cores into two different waveguides. The mode coupling theory principle is used for RI sensor{\textquoteright}s detection ability. On the centre air hole of the PCF, the analyte is placed whose refractive index is being measured. The sensor performance is analysed using a full-vector finite element method (FEM) method. Based on numerical analysis, the maximum wavelength sensitivity for the proposed PCF is 5000 nm/RIU, 4000 nm/RIU for x-polarised and y-polarised respectively and RI sensing ranges from 1.30 to 1.34 with maximum detection limit is 0.01.",
