We report an experimental realization of a highly birefringent photonic crystal fiber as a result of compressing a regular hexagonal structure. The experimental measurements estimate a group birefringence of approximately 5.5x10(-3) at 1550 nm in good agreement with the numerical results. We study the influence of compressing the regular structure at different directions and magnifications, obtaining a method to realistically enhance the phase birefringence while moderating the group birefringence.
我们报道了一种高度双折射光子晶体光纤的实验实现，这是通过压缩规则六边形结构得到的。实验测量估计在 1550nm 处的群双折射约为 5.5x10(-3)，与数值结果非常吻合。我们研究了在不同方向和放大倍数下压缩规则结构的影响，得到了一种在增强相位双折射的同时适度降低群双折射的方法。
