摘要：
A residual dispersion compensating photonic crystal fiber (PCF) is proposed having elliptical-shaped core and octagonal structure with isosceles triangular-latticed cladding. The finite element method with circular perfectly matched layer is used to investigate the guiding properties. It is demonstrated that it is possible to obtain average dispersion of -544.7 ps/(nm.km) in a wavelength range of 1.46-1.70 mu m with ultrahigh birefringence of 2.2 x 10(-2) and nonlinear coefficient of 52.7 W(-1)km(-1) at a 1.55-mu m wavelength. Besides, the proposed PCF shows confinement losses <42.4 and 0.012 dB/km for five and eight rings, respectively.
