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 …

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 …

We observe a room-temperature low-threshold transition to a coherent polariton state in bulk
GaN microcavities in the strong-coupling regime. Nonresonant pulsed optical pum** …

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

The recent surge of interest in polaritons has prompted fundamental questions about the
role of dark states in strong light-matter coupling phenomena. Here, we systematically vary …

The authors report room temperature polariton lasing at λ∼ 345 nm in a hybrid Al In N∕ Al
