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…
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…
Quantum Langevin approach for superradiant nanolasers
Igor Protsenko, Alexander Uskov, Emil C. André +2
A new approach for analytically solving quantum nonlinear Langevin equations is proposed and applied to calculations of spectra of superradiant lasers where collective effects play…
