Dynamics of an optical parametric oscillator based on dipolaritons

Abstract

The dynamics of dipolariton states in a planar microcavity under pumping of the state corresponding to the intermediate dipolariton branch has been studied. Aperiodic conversion of pump dipolaritons into dipolaritons of idler and signal modes is shown to occur under exact-resonance conditions.

Optical parametric oscillator on dipolaritons

P. I. Khadzhi, Olga F. Vasilieva

The dynamics of dipolariton states in a planar microcavity under pumping into the middle dipolariton branch is investigated. It is shown that, in the case of exact resonance, the system exhibits an aperiodic behavior whereby pump dipolaritons are converted into dipolaritons of the idler and signal modes.

Nonlinear Dynamics of a Dipolariton Optical Parametric Oscillator

Olga F. Vasilieva, Зинган Анна Петровна, V. V. Vasiliev

The dynamics of dipolariton states in a planar microcavity under pumping into the middle dipolariton branch by two laser pulses with close frequencies is investigated. It is shown that both aperiodic and periodic modes of the conversion of pump dipolaritons into idler- and signal-mode dipolaritons can take place under the conditions of exact resonance.

Nonlinear dynamics of an optical parametric exciton–polariton oscillator in a microcavity

Vasilieva, O.F., Васильева, О., Hadji, P.I. +1 more

The system of nonlinear evolution equations was obtained for describing the time evolution of densities of pump, signal, and idler microcavity polaritons. It was shown that the period and amplitude of oscillations of the polariton densities essentially depend on the initial densities of polaritons, initial phase difference, and resonance detuning. For the definite relation between the parameters, the aperiodic evolution of the system is also possible; it represents the conversion of only the part of pump polaritons, by which the evolution of the system is finished. The significant dependence of the period and amplitude of polariton oscillations on the initial phase difference evidences the possibility of the phase controlling of the polariton dynamics. The damping of the system of coherent polaritons leads to the oscillatory decay of polariton density in time, the rate of which is defined by the polariton damping constants.

Parametric oscillation in semiconductor microcavities: nonlinear and quantum effects

Jean‐Philippe Karr, A. Baas, Marco Romanelli +2 more

Abstract We report the observation of optical bistability in a semiconductor microcavity pumped at the “magic angle” above the parametric oscillation threshold. Experimental evidence is given in the form of a hysteresis cycle of the nonlinear emission as a function of the pump intensity. A model analogous to those developped for triply resonant Optical Parametric Oscillators (OPO) is in good agreement with the experimental findings. In the second part, we study the potential application of the parametric oscillation regime to quantum optics. The quantum correlations between the emitted “signal” and “idler” beams are computed. We show that very strong quantum correlations between the signal and idler polaritons can be achieved. However the quantum effects in the outgoing light fields are strongly reduced due to the large mismatch in the coupling of the signal and idler polaritons to the external photons.

Self-trapping phenomenon in exciton-polariton dynamics

Olga F. Vasilieva, P. I. Khadzhi

The polariton dynamics in a microcavity in the parametric oscillator mode, when two pump polaritons are transformed into signal and idler polaritons and vice versa, has been studied. A nonlinear differential equation is obtained, which describes the temporal evolution of pump-polariton density, the solution of which is expressed in terms of the Jacobi elliptical functions. The amplitude and period of polaritondensity oscillations are determined by the initial polariton densities and the resonance detuning. The possibility of self-trapping in exciton-polariton dynamics is predicted.

Parametric oscillation threshold of semiconductor microcavities in the strong coupling regime

Michiel Wouters, Iacopo Carusotto

The threshold of triply resonant optical parametric oscillation in a semiconductor microcavity in the strong coupling regime is investigated. Because of the third-order nature of the excitonic nonlinearity, a variety of different behaviors is observed thanks to the interplay of parametric oscillation and optical bistability effects. The behavior of the signal amplitude and of the quantum fluctuations in approaching the threshold has been characterized as a function of the pump, signal, and idler frequencies.
