Quantum analysis of a multi-frequency laser with a photonic time crystal
Igor Protsenko, Alexander Uskov
The present study considers the operation of a laser that incorporates a photonic time crystal (PTC), the purpose of which is to generate a field characterised by multiple widely s…
Effect of Tamm surface states on hot electron generation and Landau damping in nanostructures metal-semiconductor
Alexander V. Uskov, Igor V. Smetanin, Igor E. Protsenko +2
The hot electron generation in plasmonic nanoparticles is the key to efficient plasmonic photocatalysis. In the paper, we study theoretically for the first time the effect of Tamm…
Perturbation approach in Heisenberg equations for lasers
Igor E. Protsenko, Alexander V. Uskov
Nonlinear Heisenberg-Langevin equations are solved analytically by operator Fourier-expansion for the laser in the LED regime. Fluctuations of populations of lasing levels are take…
Landau damping in hybrid plasmonics
Alexander V. Uskov, Jacob B. Khurgin, Igor V. Smetanin +2
Landau Damping (LD) mechanism of the Localized Surface Plasmon (LSP) decay is studied for the hybrid nanoplasmonic (metal core/dielectric shell) structures. It is shown that LD in…
Electrostatic control over optically-pumped hot electrons in optical gap antennas
Adrian Agreda, Sviatlana Viarbitskaya, Igor V. Smetanin +3
We investigate the influence of a static electric field on the incoherent nonlinear response of an unloaded electrically-contacted nanoscale optical gap antenna. Upon excitation by…
Excitation of plasmonic nanoantennas with nonresonant and resonant electron tunnelling
Alexander V. Uskov, Jacob B. Khurgin, Igor E. Protsenko +2
A rigorous theory of photon emission accompanied inelastic tunnelling inside the gap of plasmonic nanoantennas has been developed. The disappointingly low efficiency of the electri…
