摘要
研究了单模光纤－波导之间的模场失配对光纤－波导对接耦合损耗的影响．实验测量了不同Ｔｉ膜宽度的ＬｉＮｂＯ＿３条波导的导模宽度和深度．适当选择波导制作参数可得到非常小的光纤－波导之间的耦合损耗．
In this paper we investigated the influence of mismatch between the fiber andwaveguide modes on the fiber-waveguide coupling loss. We measured the wavegu-ide mode width and depth versus the metal Ti strip width.By determining theappropriate waveguide parameters,it is found that the coupling loss between thefiber and waveguide is very low.
