A theoretical and experimental investigation of an active three-branch multimoded Ti:LiNbO(3) waveguide switch is presented. The theoretical study covers the efficiency of the electrooptic index change in a multimoded waveguide, the mode conversion occurring in a tapered transition and, finally, the power division among the branches of the switch. For the experimental characterization, the optical measurements of a device fabricated in a Z-cut LiNbO(3) crystal are presented and discussed. Several improvements as well as applications are pointed out.
本文介绍了一种有源三分支多模Ti:LiNbO(3)波导开关的理论与实验研究。理论研究涵盖了多模波导中电光指数变化的效率、锥形过渡中发生的模式转换，以及最终开关各分支之间的功率分配。为了进行实验表征，给出并讨论了在Z切割LiNbO(3)晶体中制造的器件的光学测量结果。指出了若干改进以及应用。
