Abstract

Nanostructures and metamaterials man made artificial sub wavelength structures have attracted interest in the nonlinear optics community due to the possibility of influence their linear and nonlinear electromagnetic responses however in contrary to the linear optical response the underlying physics to describe nonlinear light generation in nanostructures and the design rules to maximize the emission are still under debate Also though much research have been performed on the theoretical aspects of the effect of propagation in such nonlinear optical interactions very little have been done experimentally In my talk I share with you our recent experimental demonstrations on the nonlinear optical properties of 2D and 3D metamaterials I will give a short overview of the emerging field of nonlinear plasmonics and will briefly discuss the underlying physics behind light matter interaction at the nanoscale Then I will share with you our studies on the second harmonic and third harmonic emission from geometrical dependence plasmonic nanostructures where we showed that nonlinear scattering theory and mode matching considerations are critically important for predicting the optimal geometry of the nonlinear far field emission Also I will present our experimental work of the nonlinear propagation in a zero index optical metamaterial These materials create a phase mismatch free environment for nonlinear propagation where in contrast to existing phase matching techniques it eliminates the requirement for phase matching compensation If time allows I will share our efforts to explore the ultrafast photo induced hot carrier dynamics in plasmonic nanostructures and 2D materials
