有源光缆中光耦合系统的设计

摘要

Focusing on the coupling of the semiconductor laser and the fiber,the focus of the Gaussian beam is first understood.Then,the focusing lens is designed by ZEMAX software and the whole structure of the coupling system is simulated in the TP simulation software.The analysis shows that the coupling efficiency of the VCSEL into the fiber And 92％.Finally,the effect of lateral error on coupling efficiency is simulated.%从半导体激光器与光纤的耦合设计着手,首先了解高斯光束的聚焦,然后利用ZEMAX软件设计出聚焦透镜并在TP仿真软件中模拟出整个耦合系统的结构简图,分析得知VCSEL耦合进光纤的效率达到92％.最后,模拟了横向误差对耦合效率的影响.
