Single plasmonic split hole resonator nanostructure as an efficient nanoscale light source

We report a brief review of the results of experimental studies on the nonlinear optical interaction of laser radiation with a hybrid plasmonic nanostructure, i.e. a split hole resonator (SHR). We demonstrate second- and third-harmonic generation and mixedfrequency generation from a single SHR nanostructure. The practical application potential of an SHR nanostructure as a nanoprobe for measuring the femtosecond laser pulse duration and designing an all-optical nanodisplay is shown.
