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 …

From a theoretical point of view, we discuss a variety of phenomena linked to the spin and
polarization degree of freedom of exciton-polaritons in semiconductor microcavities. We start …

The vast majority of real-life optimization problems with a large number of degrees of
freedom are intractable by classical computers, since their complexity grows exponentially …

Although optical technology provides the best solution for the transmission of information, all-
optical devices must satisfy several qualitative criteria to be used as logic elements. In …

Microcavities are semiconductor, metal, or dielectric structures providing optical confinement
in one, two or three dimensions. At the end of the 20th century, microcavities have attracted …

A phase transition from a classical thermal mixed state to a quantum-mechanical pure state
of exciton polaritons is observed in a GaAs multiple quantum-well microcavity from the …

Polaritonic devices exploit the coherent coupling between excitonic and photonic degrees of
freedom to perform highly nonlinear operations with low input powers. Most of the current …

Polariton lasing is demonstrated on the zero-dimensional states of single GaAs/GaAlAs
micropillar cavities. Under nonresonant excitation, the measured polariton ground-state …

We report the observation of polaritonic bistability in semiconductor microcavities in the
strong-coupling regime. The origin of bistability is the polariton-polariton interaction, which …
