提出了一种新型的三芯光子晶体光纤偏振分束器的设计方案。三芯光子晶体光纤由两个相同的具有双重对称性的芯组成，两个芯之间由一个具有高双折射的芯隔开。偏振分束器是基于共振隧穿现象。采用全矢量光束传播方法进行的数值模拟表明，可以获得消光比优于-20dB、带宽为37 nm的1.9mm长的分束器。
A novel design of polarization splitter in three-core photonic crystal fibers (PCFs) has been proposed. The three-core PCF consists of two given identical cores with two-fold symmetry separated by a core with high birefringence. The polarization splitter is based on the phenomenon of resonant tunneling. Numerical simulations with a full vectorial beam propagation method demonstrate that it is possible to obtain a 1.9-mm-long splitter with the extinction ratio better than -20 dB and a bandwidth of 37nm.
