In this work, it is shown that the differential loss between the TE- and TM-polarized fundamental modes in a highly birefringent photonic crystal fiber (PCF) can be enhanced by bending the fiber. As a result, a design approach for single-mode single-polarization operation has been developed and is discussed. A rigorous full-vectorial H-field-based finite element approach, which includes the conformal transformation and the perfectly matched layer, is used to determine the single-polarization properties of such a highly birefringent PCF by exploiting its differential bending losses.
在这项工作中,研究表明,通过弯曲高双折射光子晶体光纤(PCF),可以增强TE偏振和TM偏振基模之间的差分损耗。由此,开发并讨论了一种单模单偏振操作的设计方法。采用基于严格全矢量H场的有限元方法,该方法包括保角变换和完全匹配层,通过利用其差分弯曲损耗来确定这种高双折射PCF的单偏振特性。
