Abstract

Semiconductor nanopillars and nanowires (NWs) exhibit interesting optical nonlinear effects [1,2]. These properties are attributed to the geometrical and optical properties of nanopillars which define optical field confinement [3] and the field discontinuity that contributes to bulk and surface nonlinearity [4,5]. Potential applications for these nonlinear effects include probing of the surface in nanostructures and nonlinear scanning laser microscopy.
