提出并分析了一种基于全固态多芯光子晶体光纤的改进型1×4耦合器。首先从耦合模方程出发，推导出耦合长度和耦合效率的计算公式。采用全矢量有限元法计算了耦合长度和耦合效率。其次，利用全矢量光束传播法（BPM）分析了耦合器的传输特性和性能。研究表明，有限元法和BPM法的计算结果基本一致。在λ=1.55μm时，耦合器的耦合长度为4.1mm。最大耦合效率为24.96%。在100nm波长范围内，耦合比大于22.5%。在λ=1.55μm处的偏振相关损耗为0.73dB。最后，研究了结构参数和材料折射率的微小变化对耦合器工作性能的影响。
An improved 1×4 coupler based on all solid multi-core photonic crystal fiber is proposed and analyzed. The expressions to calculate the coupling length and the coupling efficiency are deduced based on the coupled-mode equations firstly. Then a full-vector finite element method (FEM) is used to calculate the coupling length and the coupling efficiency. Next, the propagation characteristics and the performances of the coupler are analyzed through using a full vector beam propagation method (BPM). Research shows that the results derived by FEM agree with that by BPM. The coupling length of the coupler is 4.1mm at λ=1.55μm. A maximum coupling efficiency of 24.96% can be obtained. The coupling ratio is more than 22.5% over a wavelength range of 100nm. The polarization-dependent loss at λ=1.55μm is equal to 0.73dB. Finally, the influences of the micro-variation of structure parameters and the material refractive index on the working performances of the coupler are investigated.
