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…
Increased output of superradiant light-emitting diodes due to population fluctuations
Igor E. Protsenko, Alexander V. Uskov
The quantum nonlinear Maxwell-Bloch equations for a single-mode laser with a two-level active medium are solved in the LED regime without adiabatic elimination of the medium polari…
Spontaneous emission, collective phenomena and the efficiency of plasmon-stimulated photo-excitation
Igor E. Protsenko, Alexander V. Uskov, Nikolay V. Nikonorov
We find that the spontaneous and collective emissions have a strong influence on the excitation of two-level absorbers (atoms, molecules) interacting in resonance with the plasmoni…
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…
