“…Depending on the specific pump parameters, a variety of bistable and reentrant behaviors as a function of pump intensity were anticipated; in particular, the parametric threshold can be a second-order one with a continuous growth of the signal/idler intensity past the critical point, or a first-order one with a sudden jump to the OPO regime (Whittaker, 2005a;Wouters and Carusotto, 2007c). Experimental investigations of this rich nonlinear dynamics have appeared in (Baas et al, 2004b;Demenev et al, 2009).…”

This article reviews recent theoretical and experimental advances in the fundamental understanding and active control of quantum fluids of light in nonlinear optical systems. In presence of effective photon-photon interactions induced by the optical nonlinearity of the medium, a many-photon system can behave collectively as a quantum fluid with a number of novel features stemming from its intrinsically non-equilibrium nature. We present a rich variety of photon hydrodynamical effects that have been recently observed, from the superfluid flow around a defect at low speeds, to the appearance of a Mach-Cherenkov cone in a supersonic flow, to the hydrodynamic formation of topological excitations such as quantized vortices and dark solitons at the surface of large impenetrable obstacles. While our review is mostly focused on a class of semiconductor systems that have been extensively studied in recent years (namely planar semiconductor microcavities in the strong light-matter coupling regime having cavity polaritons as elementary excitations), the very concept of quantum fluids of light applies to a broad spectrum of systems, ranging from bulk nonlinear crystals, to atomic clouds embedded in optical fibers and cavities, to photonic crystal cavities, to superconducting quantum circuits based on Josephson junctions. The conclusive part of our article is devoted to a review of the exciting perspectives to achieve strongly correlated photon gases. In particular, we present different mechanisms to obtain efficient photon blockade, we discuss the novel quantum phases that are expected to appear in arrays of strongly nonlinear cavities, and we point out the rich phenomenology offered by the implementation of artificial gauge fields for photons.Comment: Accepted for publication on Rev.

“…The “stimulated” cooling via the exciton–exciton (or polariton–polariton) scattering from the reservoir state induces a coherent condensate into the polariton ground state. Some recent papers suggest that these cooling pathways result in the tens to hundreds of picosecond delay in the ground-state population. , Furthermore, the nanosecond-order renormalization dynamics of the polariton eigenstates have also been presented. , …”

“…21,22 Furthermore, the nanosecond-order renormal- ization dynamics of the polariton eigenstates have also been presented. 23,24 A different polariton cooling mechanism should be considered for the organic microcavity systems, as the Frenkel excitons have large effective masses as compared to that of the Wannier exciton, and thus their dispersion is almost flat in k space. 3 The initial state of the excitations under nonresonant pumping is also different; that is, the pumping photons are absorbed by a molecular vibrational replica of the singlet exciton (S 1 ) state, generating hot excitons.…”

Ultrafast Dynamics of Polariton Cooling and Renormalization in an Organic Single-Crystal Microcavity under Nonresonant Pumping

Microcavity systems with organic luminescent materials have a hot prospect for room-temperature cavity-polariton devices. The polariton dispersion relation of organic microcavities is significantly different from that of inorganic microcavities due to the strong localization of Frenkel excitons. Also photoexcited particles will undergo a different cooling mechanism until they reach the polariton ground state. In the characterization of efficient polariton condensates, therefore, the polariton cooling dynamics as well as the kinetics of the polariton eigenstate should be measured. Here we present experimental studies on ultrafast dynamics of cavity polaritons in an organic singlecrystal microcavity under nonresonant pumping. In time-resolved photoluminescence measurements we observed, for the first time, an ultrafast dynamics of stimulated cooling of the organic cavity polariton. Transient transmission measurement enabled us to investigate the detailed renormalization dynamics of the polariton eigenstate. The results clearly demonstrated the prospect of organic microcavities for room-temperature polaritonic devices.

“…The information on the intracavity field is obtained by MC transmission measurements. 32 The active region of the cavity is separated from the detector by a Bragg mirror that does not introduce any nonlinearity and/or spectral selectivity. Hence, the intensity of the pump pulse transmitted through the MC, I tr ͑͒, is proportional to the squared magnitude of the excited mode ͑k = k p ͒ of the intracavity electric field, ͉E QW ͑k p , ͉͒ 2 .…”

“…Within this approximation, complicated hysteresis loops in the population kinetics of pumped and scattered LPs under a nanosecond-long resonant excitation are explained qualitatively within the framework of the semiclassical model based on the Gross-Pitaevskii equations. 31,32 In contrast, no polarization conservation is observed in the stimulated scattering under the excitation with linearly or elliptically polarized light. 5,25,27,30 The intermode scattering of two linearly polarized LPs results in the change in their polarization direction to the perpendicular one.…”

Nonequilibrium transitions in the cavity polariton system are investigated under nanosecond-long pulsed excitation with linearly polarized light ͑TE or TM modes͒ near the magic angle. The main objective is to clarify the influence of the polarization-dependent properties of the polariton-polariton interaction on ͑i͒ instabilities in a driven lower polariton mode and ͑ii͒ the temporal hysteresis effects in the kinetics of the scattered polariton population. The driven mode retains the polarization of the exciting pulse and exhibits instabilities typical of the scalar ͑"spinless"͒ polariton system excited with circularly polarized light. No increase in the instability threshold for the driven mode and, as a consequence, no polarization multistability discussed for the spinor polariton system ͓N. A. Gippius et al., Phys. Rev. Lett. 98, 236401 ͑2007͔͒ is observed. Polarization of the scattering signal at the zero wave vector and that of the driven mode are mutually perpendicular, due to the polarization dependence of the exciton-exciton interaction. At the same time, at pump intensities well above the threshold of stimulated scattering, the signal exhibits a markable decrease ͑up to 25%͒ of the polarization degree during the pulse transmission.
