Abstract

Splitting ratios are measured in Ti:LiNbO3 channel waveguide branches as a function of branch angle and asymmetry. Effective index method dispersion theory is used to calculate branch parameters for each branch. The experimental results are shown to agree qualitatively with calculated results for similar planar LiNbO3 branches. Data for channel transmission loss and branch transmission are presented for ordinary modes. Prism output coupling efficiency is measured in a novel way by observing the output intensity along the prism base.
