Abstract
We report on the fabrication of periodic domain inversion on the x face of LiTaO3 by selective proton exchange and quick heat treatment. Observation of domain formation in –c‐cut LiTaO3 indicates an inside field model where electric field caused by proton diffusion reverses the orientation of domains. Based on this model, it has been found that an effective inside field to form domain inversion is also induced in x‐cut LiTaO3 by using selective proton exchange. Accordingly, periodic domain inversion at 10 μm intervals has been successfully formed on the x face of LiTaO3.Keywords
