Zusammenfassung:	A single-mode octagonal photonic crystal fiber (OPCF) is proposed to simultaneously achieve high birefringence and ultra-flattened ultra-high negative dispersion. Simulation results demonstrate that by introducing an elliptical air hole in the center of the core, it is possible to obtain a large average dispersion of -608.93 ps/nm/km with an absolute dispersion variation of -12.7 ps/nm/km over 1.46-1.625 μm wavelength bands for fundamental slow-axis mode. Besides, with optimal design parameters, a high birefringence of 1.81×10 -2 and a very low confinement loss of 0.04 dB/km are achieved at 1.55 μm. The proposed OPCF can be used in cost-effective residual dispersion compensation and optical sensors.
