Here we show that, in single perovskite CsPbI 3 nanocrystals synthesized from a colloidal
approach, a bright-exciton fine-structure splitting as large as hundreds of μ eV can be …

We present a detailed investigation of different excitonic states weakly confined in single
GaAs/AlGaAs quantum dots obtained by the Al droplet-etching method. For our analysis we …

Ultrafast transmission changes around the fundamental trion resonance are studied after
exciting ap-shell exciton in a negatively charged II-VI quantum dot. The biexcitonic induced …

We present new understanding of excitonic fine structure in close-to-symmetric InAs/GaAs
and InGaAs/GaAs quantum dots. We demonstrate excellent agreement between …

We present an experimental and theoretical study of the polarized photoluminescence
spectrum of single semiconductor quantum dots in various charge states. We compare our …

The fundamental building block of quantum information processing technologies is the
quantum-bit a'qubit.'These technologies require the ability to prepare, control, and read out a …

A detailed understanding of the population and coherence dynamics in optically driven
individual emitters in solids and their signatures in ultrafast nonlinear optical signals is of …

We present a comprehensive study of the optical transitions and selection rules of variably
charged single self-assembled InAs/GaAs quantum dots. We apply high resolution …

Using the trion as an optical probe, we uncover novel electron spin dynamics in CdSe/ZnSe
Stranski-Krastanov quantum dots. The longitudinal spin lifetime obeys an inverse power law …

New optical fiber based spectroscopic tools open the possibility to develop more robust and
efficient characterization experiments. Spectral filtering and light reflection have been used …
