Abstract
A nonlinear waveguiding optical converter in a solid state body. The waveguide is provided with compositionally differing region (domains) of dominant electrical polarization in succeeding regions transverse to the path of guided radiation.
Claims7
A nonlinear converter of electromagnetic radiation having a desired optical frequency, comprising:
- a body of solid state material;
- source means of electromagnetic radiation having one or more frequencies which are different than the desired optical frequency;
- waveguide means provided by said body for confining electromagnetic radiation;
- means for directing electromagnetic radiation from said source means into said waveguide means;
- and
- said waveguide means having a plurality of succeeding regions of differing compositions respectively providing differing states of dominant electrical polarization in succeeding regions transverse to the path of radiation guided by the same for converting radiation from said source means to output radiation having said desired optical frequency.
