通过电场传输理论,结合实验研究深入分析了基于亚波长直径微纳光纤的串、并联双环结构。建立了两种结构的数学模型,结合得到的数学公式利用Matlab进行了数据仿真。通过实验,分别得到了两种双环结构谐振腔的实际输出光谱。实验结果与理论仿真取得了较好的吻合。 Based on the theory of electric field transmission and the experimental research, the series and parallel bicyclic structures based on sub-wavelength-diameter micro-nano fibers are analyzed. The mathematical model of the two structures is established, and the data simulation is carried out by using the mathematic formula. Through experiments, the actual output spectra of two kinds of double-ring resonators are respectively obtained. The experimental results are in good agreement with the theoretical simulation.
