Abstract :
We design a novel elliptical-spiral soft-glass photonic crystal fiber (PCF) achieving simultaneous wideband high birefringence, large nonlinearity, and low chromatic dispersion. Through the optimization of the arrangement and diameter of circular air holes, the designed elliptical-spiral PCF offers high birefringence up to 0.05554, large nonlinearity up to 3089/3079 W-1 ·km-1, and low chromatic dispersion of (-95.45, 0)/(-372.6, 153.2) ps/nm/km for X/Y-polarization within a wavelength range of 1000-1800 nm.
