InSb-based THz Plasmonic Antenna for Dynamic Control of Radiative decay rate of Quantum emitters

We propose an InSb-based THz plasmonic antenna capable of dynamically tuning the radiative decay rate of an electric dipole emitter upon magnetization. The magnetized antenna supports magnetoplasmon modes that can radiatively couple to the transition dipole moment of the dipole source, resulting in multiband radiative decay rate enhancement. This proposed system holds great potential to realize tunable single photon sources with high saturation intensity in the THz regime.
