摘　　要：利用基于光束传播法的BPM软件对单模光纤连接时横向偏移进行仿真分析,通过数值计算可得到传输效率与偏移量的变化曲线及光纤连接处的光场图。分析讨论了相同光纤、不同光纤横向偏移时的连接问题。通过仿真计算得到的光场分布图可以直观地反映出横向偏移时单模光纤连接时的损耗情况。The transverse shift of single mode optical fiber connection is simulated with BPM soft-ware which is based on beam propagation method. It is obtained the curve of the transmission efficiency with the offset by numerical calculation, and can also get the fiber connection diagram of light field. This paper analyzed and discussed the connection problem of the same fiber and different optical fiber. Light field distribution is obtained by simulation calculation can intuitively reflect the loss of transverse shift of single mode optical fiber.
