Generation and signal processing in nonlinear, active and quantum meta-/nano-photonic structures in THz range

The set of the nonlinear wave transformations and generation in THz range are proposed. The approach for generation of THz oscillations by carrier drift in Graphene-(Dispersive) Dielectric structure with controlling external nmagnetic field is proposed. New idea of generation of THz plasmon-polaritons in Graphene-Hyperbolic metamaterial structure with external magnetic field and electron drift in graphene is proposed, to provide the effective control over the parameters of generated waves. Superheterodyne amplification of electromagnetic waves (EMWs) of THz range in the system dielectric-semiconductor with negative differential conductivity-dielectric is proposed. High effectiveness of the self-modulation and third harmonic generation with the scattering of THz electromagnetic waves on the controllable nonlinear resonant metasurface with periodical graphene strips on the dielectric substrate is justified by modeling.
