In this brief review, we summarize and elaborate on some of the nomenclature of polaritonic
phenomena and systems as they appear in the literature on quantum materials and …

Abstract The study of Bose–Einstein condensation effects in photonic systems has revealed
a rich phenomenology related to spontaneous coherence generation in driven-dissipative …

Perovskite crystals—with their exceptional nonlinear optical properties, lasing and
waveguiding capabilities—offer a promising platform for integrated photonic circuitry within …

Polaritons are quasiparticles that form in semiconductors when an elementary excitation
such as an exciton or a phonon interacts sufficiently strongly with light. In particular, exciton …

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 …

Exciton polaritons—quasi-particle excitations consisting of strongly coupled photons and
excitons—present fascinating possibilities for photonic circuits, owing to their strong …

Ultrafast all-optical switches and integrated circuits call for giant optical nonlinearity to
minimize energy consumption and footprint. Exciton polaritons underpin intrinsic strong …

Today, almost all information processing is performed using electronic logic circuits
operating at several gigahertz frequency. All-optical logic holds the promise to allow for up to …

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 …

Exciton-polaritons in semiconductor microcavities have become a model system for the
studies of dynamical Bose–Einstein condensation, macroscopic coherence, many-body …
