Nonlinear Optical Microscopy of Semiconductor Metal-Nanocavities
Riya Varghese, Shambhavee Annurakshita, Yaraslau Tamashevich +13
We use second and third harmonic generation microscopy to investigate the nonlinear optical response of GaAs nanocavities embedded in a gold film and compare them to bare GaAs nano…
