ABSTRACT:
A method of manufacturing a wavelength converting element forms an optical waveguide having a substantially uniform thickness and a desired size. A thin film of lithium niobate is formed on a substrate of lithium tantalate, and a mask corresponding to an optical waveguide is formed on the thin film. A proton exchange is performed on a predetermined area of the thin film through the mask. A potassium ion exchange is further performed on the proton-exchanged area, thus yielding the optical waveguide. The mode of light that propagates in the optical waveguide can be set to a low-order mode, so that the efficiency of converting the incident light to the second harmonic is improved.
