Submonolayer quantum dots combine the zero-dimensional charge-carrier confinement of self-assembled quantum dots with the large density of states of a quantum well. Electroluminescence and pump-probe experiments on a submonolayer-based optical amplif

Semiconductor optical amplifiers based on InAs submonolayer quantum dots show fast carrier recovery and large phase response. We develop a numerical model assuming strong interdot coupling and a three-dimensional carrier reservoir, which reproduces t

We investigate the energy structure of a quantum dot-in-a-well system by tracing the population of optically created excitons in pump-probe experiments and numerical simulations. The combination of a zero-dimensional and a two-dimensional substructur

Based on gain excitation spectra derived from two-color pump-probe experiments, we identify crossed exciton states formed in semiconductor nanostructures of mixed dimensionality and investigate their influence on the carrier dynamics.

A spectroscopic pump-probe method to determine the spatial shape of bound quantum states in semiconductor quantum dots is proposed. The method uses intraband transitions between the bound states and unbound continuum states in the host medium. The de

Coherence in light–matter interaction is a necessary ingredient if light is used to control the quantum state of a material system. Coherent effects are firmly associated with isolated systems kept at low temperature. The exceedingly fast dephasing
