Study of birefringence of elliptical core photonic crystal fiber using Mathieu function

摘要

The birefringence of the elliptical core photonic crystal fiber with circular pores in the cladding has beenstudied 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.
