ABSTRACT:
A first section of a waveguide channel is made of a nonlinear crystal material. A second section of the waveguide has a plurality of diverging channels. Each of the diverging channels is of a width which supports one of the modes of second harmonic generated light from the first section. First order mode second harmonic light is obtained at the end of one of the diverging channels.
