A hollow dual-core photonic crystal fiber filled with large thermo-optic coefficient liquid was analyzed. The effective refractive index, coupling length and confinement loss were investigated by the full-vector finite element method with a perfectly matched layer. Theoretical calculations and results show that the coupling length reduces linearly whenever the temperature increases, but confinement loss increases with temperature. Photonic crystal fiber filled with liquid becomes more sensitive to temperature as the wavelength reduces.
