Methods for increasing the efficiency of nonlinear optical interactions in nanostructured semiconductors Academic Article uri icon


  • Methods for increasing the efficiency of the optical second- and third-harmonic generation in gallium phosphide and silicon nanostructures formed by electrochemical etching of crystalline semiconductors are discussed. The efficiency of nonlinear optical interactions can be increased by using phase matching in anisotropic nanostructured semiconductors that exhibit form birefringence or by increasing the local field, as in scattering in macroporous semiconductors. The efficiencies of third-harmonic generation in porous silicon and of second-harmonic generation in porous gallium phosphide are found to increase by more than an order of magnitude. 2005 Pleiades Publishing, Inc.
