Two coupled CdTe quantum dots, selected from a self-assembled system, one of them
containing a single Mn ion, were studied by continuous wave and modulated …

An optical vortex is an inhomogeneous light beam having a phase singularity at its axis,
where the intensity of the electric and/or magnetic field may vanish. Already well studied are …

A promising method to investigate dark exciton transitions in quantum dots is presented. The
optical recombination of the dark exciton is allowed when the exciton state is coupled with …

We present a micropillar cavity where nondesired radial emission is inhibited. The photonic
confinement in such a structure is improved by implementation of an additional concentric …

We present direct observation of a coherent spin precession of an individual Mn 2+ ion,
having both electronic and nuclear spins equal to 5/2, embedded in a CdTe quantum dot …

We study the formation dynamics of a spontaneous ferromagnetic order in single self-
assembled Cd 1-x Mn x Te quantum dots (QDs). By measuring time-resolved …

Single dot photoluminescence excitation spectroscopy provides an insight into energy
structure of individual quantum dots, energy transfer processes within and between the dots …

We present a comprehensive photoluminescence study of the exchange interaction in self-
assembled CdTe/ZnTe quantum dots. We exploit the presence of multiple charge states in …

We study theoretically phonon-assisted relaxation processes in a system consisting of one
or two electrons confined in two vertically stacked self-assembled quantum dots. The …

We study the biexciton formation process in a single CdTe/ZnTe quantum dot. Consistently
with previous studies, we find subquadratic dependence of the biexciton photoluminescence …
