提出了一种基于双芯光子晶体光纤的新型偏振分束器。两个高双折射芯垂直布置以获得偏振选择性耦合。水平极化在两个核之间交换能量。然而，垂直偏振显示两个芯之间的耦合很小。据我们所知，这是第一次在单一材料玻璃波导中实现。基于光子晶体光纤的偏振分束器具有长度短、消光比高、带宽宽等优点。
A novel polarization splitter based on photonic crystal fibers (PCFs) with two nonidentical cores is proposed. The two highly birefringent cores are vertically arranged to obtain polarization selective coupling. The horizontal polarization exchanges its energy between the two cores. However, the vertical polarization shows little coupling between the two cores. This is achieved in single-material glass waveguides for the first time to our knowledge. The PCF-based polarization splitter exhibits many advantages such as shorter length, high extinction ratio, and wide bandwidth over its counterparts.
