In this paper, a novel photonic crystal fiber(PCF) with high birefringence and nonlinearity is designed. The characteristics of birefringence, dispersion and nonlinearity are studied by using the full-vector finite element method(FVFEM).The numerical results show that the phase birefringence and nonlinear coefficient of PCF can be up to 4.51 × 10-3and32.8972 W-1·km-1at 1.55 μm, respectively. The proposed PCF could be found to have important applications in the polarization-dependent nonlinear optics such as the pulse compress and reshaping in the C waveband.

<正> 关于古代阶级斗争的问题,作为资产阶级史学特点的有两个流派。其中的一派断定阶级斗争是原始公社制时期所固有的永恒的范畴,另一学派则反对,根本否认阶级斗争的存在。这两种见解的代表者在保护资本主义国家中存在的经济制度的目的下曲解了人类的真正历史。抹煞剥削社会中阶级矛盾的企图,特别显明地表现在天主教派代表者的著作中。他们在一切历史部门中,其中包括古代世界史,贯澈了他们镇压劳动者在其为社会进步发展斗争的方针。
