Abstract

The birefringence of the elliptical core photonic crystal fiber with circular pores in the cladding has been studied by using higher order Mathieu functions. It is observed that the birefringence decreases with decreasing wavelength. Calculated results also indicate the sensitivity to the radius of the pores in the cladding. High birefringence up to 0.0079 is obtained. The efficacy of this proposed method is proved by comparing the results.

摘要

利用高阶马蒂厄函数研究了包层具有圆形气孔的椭圆纤芯光子晶体光纤的双折射。观察到双折射随波长减小而降低。计算结果还表明了对包层气孔半径的敏感性。获得了高达0.0079的高双折射。通过比较结果证明了该方法的有效性。
