Exciton-polaritons of a hybrid type, emerging in a structure comprising semimagnetic (Mn-doped) and nonmagnetic quantum wells coupled via the microcavity optical mode are demonstrated and studied. Thanks to the susceptibility of the excitons in the m

Multi-level exciton-polariton systems offer an attractive platform for studies of non-linear optical phenomena. However, studies of such consequential non-linear phenomena as polariton condensation and lasing in planar microcavities have so far been

In this paper, we apply the angle-resolved Optically Detected Magnetic Resonance (ODMR) technique to study series of strained (Cd, Mn)Te/(Cd, Mg)Te quantum wells (QWs) produced by molecular beam epitaxy. By analyzing characteristic features of ODMR a

Coupling of quantum emitters in a semiconductor relies, generally, on short-range dipole-dipole or electronic exchange type interactions. Consistently, energy transfer between exciton states, that is, electron-hole pairs bound by Coulomb interaction,

Single impurities with nonzero spin and multiple ground states offer a degree of freedom that can be utilized to store the quantum information. However, Fe2+ dopant is known for having a single nondegenerate ground state in the bulk host semiconducto

In this work we present the band gap engineering, epitaxial growth and optical characterization of CdSe/Cd0.9Mg0.1Se and Cd0.9Mg0.1Se/Cd0.85Mg0.15Se quantum wells with a thickness ranging from 1 to 15 nm. These structures exhibit strong near-band-gap

We report on the technological and optical investigations of quantum dots (QDs) formation with magnetic ions, in particular QDs with single manganese ions. Motivation of our study was to control the ion–exciton interaction by controlling the positi
