摘要：
A chemical sensor based on dual core photonic crystal fiber (DC-PCF) is designed using COMSOL Multiphysics software based on finite element method. The two cores of the PCF are separated by an air hole and filled with different chemicals such as benzene, ethanol and water. The fundamental modes of the proposed DC-PCF are analyzed, and the maximum coupling length of the proposed sensor is 0.45 mm at 1.55 mu m wavelength. Numerical simulation results show that the proposed DC-PCF sensor with a length of 0.5 cm provides a sensitivity of 9615 nm/RIU (refractive index unit). (C) 2019 Elsevier Ltd. All rights reserved.
