Terahertz harmonic generation and nonlinear spectroscopy of metamaterial-gated/graphene resonators
We report on the terahertz (THz) harmonic generation in an active graphene/metamaterial device by using powerful ultrafast table-top THz time-domain spectroscopic systems. Complex nonlinear transmission spectra, comprising even and odd harmonics, emerge when the devices are tested with intense ultra...
