摘要：
The single mode property of a holey, index-guided two-dimensional photonic crystal fiber (PCF) is investigated using the alternate direction implicit method. The modal analysis of a three-ring elliptical air hole photonic crystal fiber is performed and compared with the equivalent three-ring circular air hole photonic crystal fiber keeping the air-fill fraction the same for both cases. The fiber is investigated for single mode operation. The effect of the rotation of the ellipse axes on these characteristics is also considered. It is observed that a PCF with elliptical air holes exhibits a better single mode property over a wider wavelength range in the optical domain. Also when the diameter of the air hole is properly catered for, they can show an endlessly single mode property.
