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…
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…
