METHOD OF FORMING POLARIZATION REVERSAL AREA, METHOD OF MANUFACTURING PSEUDO PHASE MATCHING ELEMENT AND PSEUDO PHASE MATCHING ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a method of forming polarization reversal area capable of enhancing nuclear density of polarization reversal at a low cost. SOLUTION: The method of forming polarization reversal area includes: a process of partially forming an insulation body 320 on a first area 120 which is located on a first surface of a ferroelectric crystal substrate 100 and is polarization-reversed; a process of forming a first electrode 242 on the first area 120 and on the insulation body 320; and a process of turning the first area 120 into the polarization reversal area 124 by applying a voltage between a second electrode 220 and the first electrode 242 formed on the second surface as an opposite surface to the first surface.
