Abstract
A half-wave thin film was formed on the facet of a proton-exchanged wa veguide by the oblique deposition of Ta2O5. Planar-type butt coupling of the waveguide on the z-cut LiTaO3 substrate to the AlGaAs laser dio de in transverse electric mode oscillation was realized with coupling efficiency as high as 53%.
