초록

We investigated the preparation and guided-mode properties of $Ti:LiNbO_3$ waveguides which were fabricated by Ti in-diffusion. The diffusion method to reduce the Li out-diffusion was proposed. The optical guided-mode and propagation loss based on butt-coupling pigtailed with PMF-input were measured. How to improve the polishing grade of waveguide endfaces is newly proposed in this paper. To show the mode propagations, the BPM simulations of channel waveguide are described.
