- Abstract: Radiative cascades emit correlated photon pairs, providing a pathway for the
generation of entangled photons. The realization of a radiative cascade with
impurity atoms in semiconductors, a leading platform for the generation of
quantum light, would therefore provide a new avenue for the development of
entangled photon pair sources. Here we demonstrate a radiative cascade from the
decay of a biexciton at an impurity-atom complex in a ZnSe quantum well. The
emitted photons show clear temporal correlations revealing the time--ordering
of the cascade. Our result establishes impurity atoms in ZnSe as a potential
platform for photonic quantum technologies using radiative cascades.

spectroscopy [0.0]
The radiative quantum cascade, i.e. the consecutive emission of photons from a ladder of energy levels, is of fundamental importance in quantum optics.
Here, we use exciton polaritons to explore the cascaded emission of photons in the regime where individual transitions of the ladder are not resolved.
Remarkably, the measured photon-photon correlations exhibit a strong dependence on the polariton energy, and therefore on the underlying polaritonic interaction strength.

of the population inversion: transition to lasing in the class-B limit [62.997667081978825]
No class-B quantum density-matrix model is available to date, capable of accurately describing coherence and photon correlations within a unified theory.
Here we carry out a density-matrix theoretical approach for generic class-B lasers, and provide closed equations for the photonic and atomic reduced density matrix in the Fock basis of photons.
This model enables the study of few-photon bifurcations and non-classical photon correlations in class-B laser devices, also leveraging quantum descriptions of coherently coupled nanolaser arrays.
