ABSTRACT:
An excellent periodic domain-inverted structure formed on a ferroelectric optical single crystal substrate is provided having an improved crystalline property of the substrate and an improved resistance to optical damage and output of the domain-inverted structure and the like optical waveguide structure by forming protruded and recessed portions on a single-domained ferroelectric optical single crystal substrate 1, growing a film of a ferroelectric optical single crystal film 4 on the respective recessed portion of the single crystal substrate 1 by a liquid phase epitaxial growing process. At that time, the Curie temperature of the film 4 is lower than the liquid phase epitaxial growing temperature of the film 4, and the Curie temperature of the substrate 1 is higher than the liquid phase epitaxial growing temperature of the film 4, and the film 4 is polarized in an opposite direction to the polarization direction of the substrate 1.
