摘　　要：光纤与光波导之间的耦合技术一直都是光通信领域的研究热点,被广泛应用于光网络组件的对准和调光。本文基于高斯光束的模场匹配理论,提出了一种He-Ne激光到LiNbO3波导的间接耦合新方法,利用ZEMAX软件设计优化了三块组合透镜对光束进行准直和整形,最终使激光经过透镜组的耦合效率可达到80%以上。The coupling technology between optical fiber and waveguide has been a hot topic in the field of optical communication, which has been widely used in the alignment and dimming of optical network components. Based on the mode field matching theory of Guassian beam, a new indirect coupling method between He-Ne laser and LiNbO3 waveguide has proposed in this paper. And using ZEMAX software to optimized three lens combinations for collimating and shaping beams. Finally, the coupling efficiency of the laser passing through the lens group can reach more than 80%.
