A simple silicon-core microfiber has been proposed to simultaneously achieve an ultrahigh birefringence order of , a large nonlinear coefficient, and two zero-dispersion wavelengths. The full-vector finite-element method with a circular perfectly matched layer boundary is used to simulate the properties of our proposed microfiber. It is suitable to achieve two zero-dispersion wavelengths of and for the -polarized mode and of and for the -polarized mode, when the major and minor diameters are, respectively, and , and the radius of the silicon core is about 135.35 nm. Meanwhile, the nonlinear coefficients of two nondegenerated modes at the wavelength of 1550 nm are and , respectively, and the maximum birefringence is about at 1550 nm wavelength. Therefore, our proposed silicon-core microfiber exhibits excellent polarization and nonlinearity performance, which enables it to be used for polarization-maintaining nonlinear signal processing, such as supercontinuum spectrum generation, parametric amplification, optical nonlinear sensor, and so on.
