“…In those earlier studies, the pump pulse is typically along the long axis direction of the gas sample that is typically about several centimeters long [17,19]. Theoretical analysis included both propagation retardation and transverse diffractive effects [25,26]. In the recent MIT experiment, the sample size is much smaller and the pump pulse is along the transverse direction of the long axis [4].…”

We propose a new formulation for atomic side mode dynamics from super-radiant light scattering of trapped atoms. A detailed analysis of the recently observed super-radiant light scattering from trapped bose gases [S. Inouye et al., Science 285, 571 (1999)] is presented. We find that scattered light intensity can exhibit both oscillatory and exponential growth behaviors depending on densities, pump pulse characteristics, temperatures, and geometric shapes of trapped gas samples. The total photon scattering rate as well as the accompanied matter wave amplification depends explicitly on atom number fluctuations in the condensate. Our formulation allows for natural and transparent interpretations of subtle features in the MIT data, and provides numerical simulations in good agreement with all aspects of the experimental observations.

“…The delay time statistics and timing jitter of SR pulses in atomic (molecular) ensembles have been thoroughly studied previously by both classical and quantum mechanical approaches. In some conditions, the standard deviation of the SR delay time was found to be 10-12 % [30,31]. However, the results of previous studies can hardly be applied to our case of semiconductor laser structures.…”

We show that superradiant emission (SR) in semiconductor laser diode structures is governed by the master equation of the form of Ginzburg-Landau equation or Gross-Pitaevskii equation for a phase transition to coherent matter state. We conjectured condensation of one-dimensional longitudinal lower polaritons with effective mass of 10 −11 the mass of free electron. Two different regimes of SR emission and polariton condensation are predicted, one of which exhibits some characteristic features of the Dicke superradiance in atomic gases. The predictions of analytic model are confirmed by the results of numerical simulations based on Maxwell-Bloch equations, utilizing InGaN/GaN heterostructure quantum well as a model system.

“…ε -средняя (по резонатору и по частотам генерации) диэлектрическая проницаемость матрицы активной среды, усредненный фактор заполненияŴ ≤ 1 учитывает возможное отличие профиля моды от профиля концентрации активных центров [15][16][17]. Несмотря на то что обсуждавшееся ранее время жизни фотона T E в " холодном" (т. е. при n ≡ 0) резонаторе играет важнейшую роль в динамике лазера, соответствующая безразмерная скорость релаксации поля в различных модах Ŵ E = 1/(ν c T E ) явно в уравнениях не фигурирует, а задается неявно брэгговской модуляцией диэлектрической проницаемости и граничными условиями на зеркалах лазерного резонатора с коэффициентом отражения R (для простоты мы не учитываем возможные омические и дифракционные потери):…”

We investigate the features of multimode steady-state generation of the superradiant heterolasers which have an active medium formed by the quantum dots with long incoherent relaxation time and a cavity of a combined Fabry-Perot type with a distributed feedback of the counter-propagating waves. We show that a quantum-coherent dynamics of the optical dipole oscillations and a population inversion of the working levels in an ensemble of the quantum dots with a strong inhomogeneous broadening of a spectral line may lead to a simultaneous lasing of modes with a various degree of phasing and/or correlation and with qualitatively different dynamical behavior, including quasi-stationary, metastable, self-modulated, pulsed-periodic, quasi-chaotic ones.
