ABSTRACT:
An optical wavelength conversion device is constituted by a pair of substrates disposed facing each other, and an optical waveguide formed of a nonlinear optical material and disposed between the substrates, thereby to convert a fundamental wave entering the optical wavelength conversion device formed to a second harmonic which is phase matched by Cherenkov radiation. At least one of the substrates is provided with a grating for entry of the fundamental wave, which is formed on a surface contacting the optical waveguide, and/or with a grating for radiation of the second harmonic, which is formed on a surface opposite to the surface contacting the optical waveguide. The optical wavelength conversion device is made by forming grooves on the substrates, filling a slight space between the substrates with a crystallizable organic nonlinear optical material, and gradually crystallizing the optical material.
