摘要： E.A.J.Marcatili利用矩形截面的假设,通过解麦克斯韦方程,得到在条波导中传播的Epqx模和Epqy模是分立的,传播常数受到光波长、波导深度、波导宽度及波导区和周围折射率值的影响.这样,在所要求的工作光波段里,只要合理地安排好波导的几何尺寸和折射率差,便可得到单模波导.

Abstract: This paper gives the details of the fabrication and testing of the single-mode-LiNbO3 channel waveguide and the waveguide phase shifter. A novel method for suppressing Li2O out-diffusion in the Ti:LiNbO3 waveguide is wsed. The experimental V5 of the waveguide phase shifter is 5 v.
