METHOD FOR MANUFACTURING PERIODICAL POLARIZATION REVERSAL STRUCTURE, AND OPTICAL DEVICE

摘要

PROBLEM TO BE SOLVED: To increase the width of a periodical polarization reversal structure. SOLUTION: One comb-shaped electrode 39A and the other comb-shaped electrode 39B, placed opposite to each other, are disposed on one principal surface of a ferroelectric single crystal substrate. Electrode pieces 23A of the one comb-shaped electrodes 39A and electrode pieces 23B of the other comb-shaped electrodes 39B are placed opposite to one another via a gap 27. The periodical polarization reversal structure is formed by forming a uniform electrode on the other principal surface of the substrate and applying a voltage between the comb shaped electrodes and the uniform electrode.
