ABSTRACT:
An optical waveguide second harmonic generating element comprises a KTP single-crystal substrate sliced at a z-plane, a plurality of polarization reversal areas having spontaneous polarization, whose direction is reversed, and formed periodically along a predetermined direction on the z-plane of the substrate, and a channel waveguide, extending along the predetermined direction across polarization reversal areas, for propagating a light.
