Quantum analysis of multi-frequency laser with 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…
Population fluctuation mechanism of the super-thermal photon statistic of LEDs with collective effects
Igor E. Protsenko, Alexander V. Uskov
We found that fluctuations in the number of emitters lead to a super-thermal photon statistics of small LEDs in a linear regime, with a strong emitter-field coupling and a bad cavi…
Single photon optical bistability
Igor E. Protsenko, Alexander V. Uskov
We investigate the bistability in a small Fabry-Perot interferometer (FPI) with the optical wavelength size cavity, the nonlinear Kerr medium and only a few photons, on average, ex…
Quantum fluctuations in the small Fabry-Perot interferometer
Igor E. Protsenko, Alexander V. Uskov
We consider the small, of the size of the order of the wavelength, interferometer with the main mode excited by a quantum field from a nano-LED or a laser. The input field is detun…
Oscillator laser model
Igor E. Protsenko, Alexander V. Uskov
A laser model is formulated in terms of quantum harmonic oscillators. Emitters in the low lasing states are usual harmonic oscillators, and emitters in the upper states are inverte…
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…
