Abstract.  A simple hexagonal photonic crystal fiber is proposed to simultaneously achieve ultrahigh birefringence, large nonlinear coefficient, and two zero dispersion wavelengths (ZDWs). The finite element method with circular perfectly matched layer boundary condition is used to simulate the designed structure. Simulation results show that it is possible to achieve two closely lying ZDWs of 1.08 and 1.29  μm for x-polarization with 0.88 and 1.20  μm for y-polarization modes, respectively. In addition, an ultrahigh birefringence of 3.15×102 and a high nonlinear coefficient of 58  W1km1 are also obtained at the excitation wavelength of 1.55  μm. The proposed fiber can have important applications in supercontinuum generation, parametric amplification, four-wave mixing, and optical sensors design.
