摘要:
基于光束传播法,提出了计算大孔径塑料锥形过渡器的理论分析模型.采用Crank-Nicholson差分格式对耦合器截面进行剖分,分别从过渡器的大小两端作为输入端,讨论了圆锥角度以及过渡器长度对过渡器的损耗和耦合效率的影响.改变过渡器的角度(1°~9°)和过渡器长度(250~1 900 μm)进行模拟和计算.当过渡器的圆锥角度为6°,过渡器长度L=1 500 μm时,锥形过渡器的耦合效率最好.本文计算出的锥形耦合器传输端面的场强分布,可用于耦合器的设计选择.
Abstract:
Based on beam propagation method(BPM),an analytical model for the tapered polymer optical fiber connector with large dimension is presented. Using Crank-Nicholson difference scheme, the section of coupler was analyzed. Affections of the coupling length and the cone angle of the taper section for the connector on the insert loss and split ratio were discussed in details from the big and small section respectively. According to the results of simulations to the tapered connector with different lengths(250-1 900 μm)and cone angles(1°-9°), it is concluded: when the cone angle is 6° and the coupling length is 1 500 μm,the performance of the coupler is good. The probation field distribution of the connector calculated in the paper is beneficial to the design of the connector.
