Abstract
We experimentally demonstrate very efficient non-phase-matched second- and third-harmonic generation from a macroporous GaP. The generated second-harmonic signal is independent of crystallographic orientation, and its enhancement is believed to be due to the light localization for which conditions exist in the studied samples of porous GaP. The nonlinear optical results are correlated with linear optical scattering studies and atomic-force microscopic images of the studied surfaces.
