摘要:

基于全矢量平面波方法,以聚甲基丙烯酸甲酯为基材,设计了一种高双折射光子晶体光纤,并对其传输性质和偏振特性进行了数值模拟。结果表明,椭圆孔六角点阵聚合物光子晶体光纤的双折射是由于包层的不对称性引起的全局双折射,通过调节椭圆率,发现该光纤可以以单模方式在一合适波段运行,该波段与聚合物光纤的低损耗通信窗口一致。并且在 时,其双折射最高可达 。该研究结果为高双折射聚合物光子晶体保偏光纤的制备提供了理论依据。

Abstract:

The polarization properties and propagation characteristics of polymer photonic crystal fibres with elliptical air-holes and hexagonal structure are investigated by using the full vectorial plane wave method. The results show that the birefringence of the fibre is induced by asymmetries of the cladding. Moreover, by adjusting the elliptical ratio of cladding, we find the optimized design parameters of the fiber with birefringence, operating in a single mode regime at an appropriate wavelength range. The range of wavelength is consistent with the communication windows of polymer optical fibres, and elliptical ratio of cladding , this fibre is able to exhibit high birefringence of .This conclusion is useful for preparing high birefringence polymer photonic crystal fibers.

Key words: fiber and waveguide optics, polarization properties, full vectorial plane wave method, polymer, optical fibers, high birefringence
