提出了一种基于双芯高双折射光子晶体光纤的高消光比全圆形空气孔短长度偏振分束器。采用全矢量有限元法（FEM）和半矢量光束传播法（BPM）数值研究了几何参数对耦合偏振依赖性、耦合长度比和传输特性的影响。模拟结果表明，通过适当调整空气孔的尺寸，可以将激发波长为1.55 μm时的共光比优化为3/2和4/3，以满足偏振模分裂的充分条件。对于两种最佳结构，在工作波长为1.55 μm时，x和y偏振模的分离分别在1.41 mm和2.89 mm的短长度内实现。在λ = 1.55μm处的消光比分别为97.7dB和88.1dB，消光比优于15 dB的波长带宽分别为107和82 nm。
We propose an all circular-air-hole short-length polarization beam splitter (PBS) with high extinction ratio based on dual-core highly birefringent photonic crystal fiber (PCF). The impacts of geometrical parameters on the coupling polarization dependence, coupling length ratio (CLR), and propagation property are numerically investigated by the full-vector finite element method (FEM) and the semi-vector beam propagation method (BPM). From simulation results, it is seen that CLRs at the excitation wavelength of 1.55 μm can be optimized to be closed to the desired values of 3/2 and 4/3 to satisfy the sufficient condition of splitting polarized modes by appropriately tailoring the air-hole sizes. For the two optimal structures, the separation of xand y-polarized modes can be achieved in short lengths of 1.41 mm and 2.89 mm at the operating wavelength of 1.55 μm, respectively. Furthermore, the extinction ratios at λ = 1.55μm are estimated to be 97.7 dB and 88.1 dB, and the wavelength bandwidths of extinction ratio better than 15 dB are about 107 and 82 nm, respectively.
