Optical waveguides realised in z-cut, 5 mol% Mg-doped, congruent LiNbO3 using Etching During Indiffusion of Ti

We report the fabrication of optical waveguides in z-cut 5 mol% Mg-doped congruent LiNbO
₃
using the etching during indiffusion of Ti (EDIT) technique. Waveguiding is demonstrated at 633 nm and 1550 nm and effective index and loss measurements of waveguide at 1550 nm are also presented.
