LiNbO3 waveguide substrates are terminated in out-of-plane 45°-angled knife edges for the first time to our knowledge. This termination causes the guided wave to be totally internally reflected with excellent efficiency into or out of the waveguide surface, which allows new approaches for hybrid integration.
