ABSTRACT:
A light wavelength converter which includes a laser beam source for radiating fundamental waves, a first optical waveguide formed on a substrate so as to convert the fundamental waves into harmonics which are radiated through the substrate, a grating coupler provided on the substrate so as to receive the harmonics propagated through the substrate, and a second optical waveguide formed on the substrate, the second optical guide being connected to the grating coupler so as to radiate the harmonics outside.
