Bose–Einstein condensation describes the macroscopic occupation of a single-particle
mode: the condensate. This state can in principle be realized for any particles obeying Bose …

Active optical elements with ever smaller footprint and lower energy consumption are central
to modern photonics. The drive for miniaturization, speed and efficiency, with the …

Abstract A Bose–Einstein condensate (BEC) is a state of matter in which extensive collective
coherence leads to intriguing macroscopic quantum phenomena. In crystalline …

Conventional semiconductor laser emission relies on stimulated emission of photons,, which
sets stringent requirements on the minimum amount of energy necessary for its operation,. In …

Under adequate conditions, cavity polaritons form a macroscopic coherent quantum state,
known as polariton condensate. Compared to Wannier-Mott excitons in inorganic …

We demonstrate experimentally the condensation of exciton polaritons through optical
trapping. The nonresonant pump profile is shaped into a ring and projected to a high quality …

Abstract The Bose–Einstein condensate of exciton-polaritons has emerged as a unique,
coherent system for the study of non-equilibrium, macroscopically coherent Bose gases …

We investigate the phase coupling between spatially separated polariton condensates
under nonresonant optical pulsed excitation. In the simple case of two condensates, we …

Although organic polariton condensation has been recently demonstrated, they only utilize
the photon part of polaritons and ignore the excitonic contribution because the polariton …

We report a time-resolved study of the thermalization dynamics and the lasing to photon
Bose-Einstein condensation crossover by in situ monitoring the photon kinetics in a dye …
