摘要：
A light wavelength converter which includes a light source for emitting fundamental waves having a desired wavelength, a first loop-shaped optical waveguide for converting the fundemental waves into harmonics, and a second optical waveguide for receiving the light from the source, wherein the two waveguides are coupled by an optical directional coupler.
