Ultrafast Nonlinearity and Time-dependent Quadratic Nonlinear Response in Ultrathin Hetero-nanostructures
Ultrafast nonlinearity is a basis for the development of time-varying media, in particular those operating in the epsilon-near-zero regime. Here, we will discuss how to control the time response of a free-electron nonlinearity and demonstrate two orders of magnitude stronger modulation of the second-harmonic generation than the linear optical properties.
