Abstract
We have investigated the modal birefringence behaviour of a near-elliptic core index-guiding photonic crystal fiber (PCF) intended for realizing high birefringence characteristics. For this analysis, we have devised a semi-vectorial finite difference (FD) algorithm in combination with the perturbation correction technique of mode calculation. The approach yields accurate results, simple to implement, and much faster than any of the existing methods. The effectiveness of our design analysis has been verified by comparing the results with otherwise known solutions. Using this analysis as a design recipe, we have realized PCF of reasonably high birefringence characteristics.
