【摘要】 本文直接从光射线轨迹方程出发,数值求解任意折射率 GRIN棒中射线轨迹,从而得到最低插入损耗下的最佳结构参量。文中详细介绍波分复用器结构参量的优化设计方法。该法也适合于 GRIN 棒型其它光纤无源器件。设计值与实验值一致性较好。更多还原

【Abstract】 In this paper,starting from the ray equation,by means of numerial compu- tation,we have get ray trajectories in GRIN rod lens with arbitrary index profile and then obtained the optimun structure parameters of the wavelength multiplexer when its insertion loss is minimum.The method for design of optimum strucrure parameters of wavelength multiplexer is introduced in detail. This method is also applicable to other passive optical fiber devices including GRIN rod lens.The experimental results are in good agreement with the computation.更多还原
