Working principle of far-field super-resolution imaging based on nonlinearly excited evanescent waves. (a) Schematic of the far-field super-resolution imaging process with localized evanescent-wave illumination excited by FWM process at the interface. The zoomed inset shows the FWM process takes place on nonlinear medium's interface (b) Mechanism illustrated in Fourier space.
