In this paper we report on the theoretical analysis and fabrication of a dual-core microstructured polymer optical fiber (mPOF) and demonstrate how the coupling characteristics of a dual-core mPOF may be a key factor to assess the quality of the fabrication process. The coupling characteristics of this fiber have been tested and, for comparison purposes, simulations regarding the effects of inaccuracies during the manufacturing process were carried out to evaluate the fabrication quality. Results indicate that theoretical, simulation and experimental data are in good agreement, which highlights the uniformity of the microstructure along the fiber and the quality of its fabrication process. In fact, the manufactured mPOF reached a coupling efficiency up to 95.26%, which makes this mPOF appealing for applications in which highly efficient power couplers are required.
在本文中，我们报告了一种双芯微结构聚合物光纤（mPOF）的理论分析与制造，并展示了双芯mPOF的耦合特性如何可能成为评估制造过程质量的关键因素。已对该光纤的耦合特性进行了测试，并且为了进行比较，针对制造过程中的不精确性影响进行了模拟，以评估制造质量。结果表明，理论、模拟和实验数据吻合良好，这突出了沿光纤微结构的均匀性及其制造过程的质量。实际上，制造出的mPOF实现了高达95.26%的耦合效率，这使得这种mPOF在需要高效功率耦合器的应用中颇具吸引力。
