这封信的目的是介绍和数值研究的操作的一种新型的偏振无关的分裂器的基础上高度双折射的双芯光子晶体光纤（PCF），它允许波长复用在1.3和1.55妈妈。设计过程遵循严格的合成算法的基础上精确方程描述的波长去耦机制和全矢量有限元以及光束传播方法精确建模的PCF。新提出的PCF分离器的典型特性是耦合长度为9.08 mm，可用的光学带宽定义在-20 dB水平，分别为5.5和2 nm，约1.3和1.55 μ m
The objective of this letter is to introduce and numerically investigate the operation of a novel type of polarization-independent splitter based on highly birefringent dual-core photonic crystal fiber (PCF), which allows wavelength multiplexing at 1.3 and 1.55 mum. The design procedure follows a rigorous synthesis algorithm based on exact equations for describing the wavelength decoupling mechanism and on full-vector finite element as well as beam propagation methods for accurate modeling of PCFs. Typical characteristics of the newly proposed PCF splitter are coupling length of 9.08 mm and available optical bandwidths defined at a level of -20 dB of 5.5 and 2 nm around 1.3 and 1.55 mum, respectively
