Abstract
Abstract A type of total internal reflection photonic crystal fiber (TIR-PCF) with high birefringence and multiple zero dispersion wavelengths is presented. The optical characteristics are numerically investigated by using the full-vector finite element method. Results show that, by setting the geometrical parameters, the mode birefringence can reach to 2.28 × 10−2 at the wavelength of 1.55 μm, and two zero-dispersion wavelength points appear in the infrared band, one of which emerges near the wavelength of 1.55 μm. It provides a new structure for large birefringence photonic crystal fiber with multiple zero-dispersion wavelengths, and it could be widely used in the fields of fiber polarization control, dispersion management, super-continuum generation and soliton propagation.
