Phase transitions to quantum condensed phases—such as Bose–Einstein condensation
(BEC), superfluidity, and superconductivity—have long fascinated scientists, as they bring …

Semiconductor microcavities, in which strong coupling of excitons to confined photon modes
leads to the formation of exciton–polariton modes, have increasingly become a focus for the …

The imminent limitations of electronic integrated circuits are stimulating intense activity in the
area of nanophotonics for the development of on-chip optical components, and solutions …

We measure the polariton distribution function and the condensation threshold versus the
photon-exciton detuning and the lattice temperature in a CdTe microcavity under …

We observe dramatic changes in the near-field and far-field emission from a semiconductor
microcavity excited by a pulsed and nonresonant optical pump with varying power. Above a …

We report on evidence for polariton condensation out of a reservoir of incoherent polaritons.
Polariton population and first-order coherence are investigated by spectroscopic imaging of …

In highly doped semiconductor quantum wells (QWs), electrons populate various energy
states from different subbands and, therefore, several optical intersubband transitions …

In a polariton, laser coherent monochromatic light is produced by a low-energy state of the
system at the bottom of a polariton'trap', where a condensate of polaritons is formed …

In this chapter we address a complex set of optical phenomena linked to the spin dynamics
of exciton polaritons in semiconductor microcavities. When optically created, polaritons …

Excitons coupled to light in microcavities form exciton–polaritons (polaritons) having very
light effective masses. These 2-dimensional quasiparticles exhibit local condensation or …
