Active Control of Plasmon-Exciton Coupling in MoS2-Ag Hybrid Nanostructures

Optically‐controllable plasmon–exciton coupling is achieved in MoS2–Ag hybrid nanostructures, facilitated by a photoexcited exciton‐induced modulation of MoS2 dielectric function. The white light spectra of surface plasmon resonances are gradually red‐shifted by increasing incident laser power. This...

Zusammenfassung:Optically‐controllable plasmon–exciton coupling is achieved in MoS2–Ag hybrid nanostructures, facilitated by a photoexcited exciton‐induced modulation of MoS2 dielectric function. The white light spectra of surface plasmon resonances are gradually red‐shifted by increasing incident laser power. This spectroscopic tunability can be controlled by the near‐field coupling strength and polarization state of light. It can also be selectively applied to control plasmonic dark modes.
