We have designed a polarization-maintaining tapered fiber which shows an extremely large structure birefringence due to an elliptical cross section in the waist region. The propagation constant and group velocity dispersion were calculated based on the Maxwell equations and by using Mathieu functions. The zero dispersion wavelength of the odd dominant mode is located at a larger wavelength than that of the even dominant mode. With this polarization-maintaining tapered fiber, the efficiency of supercontinuum generation can be enhanced and the resulting supercontinuum is highly polarized. The spectral and temporal properties of the supercontinuum generation in polarization-maintaining tapered fiber are simulated by solving the nonlinear Schrödinger equation.
