Surface Optical Nonlinearity in GaP Nanopillar Waveguides
2012 (English)Conference paper (Refereed)
Second harmonic generation in GaP nanopillars is investigated by polarization measurements and light confinement analysis. Effective thickness of the nonlinear surface region is ~ 10nm and the corresponding nonlinear coefficient 20 times larger than in bulk.
