TL;DR: In this paper, photon correlation measurements were used to characterize the corresponding critical slowing down of nonequilibrium dynamics in GaAs cavity-polaritons, which can be described as a first-order dissipative phase transition.

TL;DR: A large reversible and controllable electromechanical wavelength tuning (> 15 nm) of the cavity modes is demonstrated and a design to increase the flexibility of the structure is discussed.

TL;DR: In this paper, a cascade design with 3 InAs quantum wells (QWs) in the electron injector was used to achieve a threshold current density of 940 A/cm2 at a record wavelength of 7μm for ICLs operating in pulsed mode at room temperature.

TL;DR: In this paper, the polarization dynamics of a spatially expanding polariton condensate under nonresonant linearly polarized optical excitation were studied and the formation of non-trivial spin textures in the form of a quadruplet polarization pattern both in the linear and circular Stokes parameters, and an octuplet in the diagonal Stokes parameter.

TL;DR: In this article, the spontaneous emission rate of single InAs quantum dots embedded in a double-membrane photonic crystal cavity was demonstrated by the electromechanical tuning of the cavity resonance.
