A novel design of highly birefringent tellurite liquid crystal photonic crystal fibres (PCFs) with low confinement loss and high non‐linearity is introduced. The simulation results are obtained by using full‐vectorial finite‐difference method. The analysed parameters are birefringence, hybridness, effective mode area and non‐linearity for the two fundamental polarised modes. Significant improvements of PCFs in terms of birefringence, confinement losses and non‐linearity are demonstrated by careful investigation of the structure geometrical parameters and temperature. The reported design has high birefringence of 0.09094 and high non‐linearity γ of 2502 and 1900 W −1 km −1 for the quasi‐transverse electric and quasi‐transverse magnetic modes, respectively, at the operating wavelength of 1.55 µm with low losses for the two fundamental polarised modes.
