ABSTRACT:
A wavelength converting element comprises; an X or Y-out substrate made of lithium tantalate crystal or lithium niobate crystal having a major surface containing a Z-axis of the crystal; polarization inversion layers formed the major surface each extending in the Z-axis and treated by applying an electric field of direct current to the substrate wherein the electric field of direct current contains a field component toward an inverse direction of the Z-axis intersecting at an angle of .theta. in a range of 0.degree.<.theta.<90.degree. with respect to the Z-axis during an annealing of the substrate; and an optical waveguide intersecting with the polarization inversion layers formed and treated on the major surface of the substrate, thereby achieving deep polarization inversion layers with a fine pitch and width on a Y or X-cut surface of the crystal substrate to satisfy a high QPM condition to produce a wavelength converting element capable of direct coupling with a semiconductor laser and having a high optical converting efficiency.
