ABSTRACT:
A method for producing domain reversals at predetermined periods deep into a MgO-LN substrate or a MgO-LT substrate in a highly controllable manner without entailing the destruction of crystals of the substrate. Proton-exchanged regions are produced in a predetermined pattern on a unipolarized MgO-LN substrate, and a substrate having a doping level of MgO ranging between 3 mol. % and 9 mol. % is used as the MgO-LN substrate when these proton-exchanged regions are changed to localized domain reversals by applying an electric field to the proton-exchanged regions from a high voltage power source, e.g., via a corona wire.
