提出了一种新的光子晶体光纤包层设计，可同时实现超扁平大负色散和超高双折射。数值结果证实了所提出的PCF在S+C+L+U波段表现出超平坦的大负色散，平均色散约为-558.96 ps/nm/km，在1460 ~ 1675 nm （215 nm带宽）范围内的绝对色散变化为9.7 ps/nm/km。此外，在1500 nm波长处也实现了0.0299的超高双折射。
We present a new cladding design for photonic crystal fiber (PCF) on a decagonal structure to simultaneously achieve ultra-flattened large negative dispersion and ultrahigh birefringence. Numerical results confirm that the proposed PCF exhibits ultra-flattened large negative dispersion over the S+C+L+U wavelength bands and average dispersion of about -558.96 ps/nm/km with absolute dispersion variation of 9.7 ps/nm/km from 1460 to 1675 nm (215 nm bandwidth). Moreover, ultrahigh birefringence of 0.0299 is also achieved at a 1500 nm wavelength.
