Collective fluid dynamics of a polariton condensate in a semiconductor microcavity
Using a coherent excitation triggered by a short optical pulse, a macroscopically degenerate state of polaritons are created that can be made to collide with a variety of defects present in the microcavity and opens the way to the investigation of new phenomenology of out-of-equilibrium condensates.
Exciton–polaritons in van der Waals heterostructures embedded in tunable microcavities
The results pave the way for room-temperature polaritonic devices based on multiple-quantum-well van der Waals heterostructures, where polariton condensation and electrical polariton injection through the incorporation of graphene contacts may be realized.
Observation of bright polariton solitons in a semiconductor microcavity
Microcavity polaritons are composite half-light half-matter quasiparticles, which have recently been demonstrated to exhibit rich physical properties, such as nonequilibrium condensation, parametric
Intrinsic decoherence mechanisms in the microcavity polariton condensate.
The fundamental mechanisms which control the phase coherence of the polariton Bose-Einstein condensate (BEC) are determined. It is shown that the combination of number fluctuations and interactions
Persistent currents and quantized vortices in a polariton superfluid
Similar to atoms in cold gases, exciton–polaritons in semiconductor microcavities can undergo Bose–Einstein condensation, but under non-equilibrium conditions. Now, quantized vortices and persistent
Spin Textures of Exciton-Polaritons in a Tunable Microcavity with Large TE-TM Splitting.
Depending on the strength and anisotropy of the cavity confining potential and of the TE-TM induced splitting, the exciton-polariton emissions exhibit either spin-vortex-like patterns or linear polarization, in good agreement with theoretical modeling.
Two-Dimensional Metal–Chalcogenide Films in Tunable Optical Microcavities
Integration of quasi-two-dimensional (2D) films of metal–chalcogenides in optical microcavities permits new photonic applications of these materials. Here we present tunable microcavities with
Exciton polaritons in semiconductor waveguides
We report the observation of strong coupling between quantum well excitons and a guided mode of a semiconductor planar waveguide by observation of anticrossing in the dispersion. Strong spatial
Dark Solitons in High Velocity Waveguide Polariton Fluids.
A continuous wave nonlinearity more than ten times that on picosecond time scales, arising due to interaction with the exciton reservoir is deduced.
Nonlinear dynamics of polariton scattering in semiconductor microcavity: Bistability vs. stimulated scattering
We investigate an unusual behavior of the parametric polariton scattering in a semiconductor microcavity (MC) under a strong cw resonant excitation: The maximum of the scattered signal above the
