Nonequilibrium nuclear-electron spin dynamics in semiconductor quantum dots (2007)
Feng, D. H., Akimov, I. A., Henneberger, F.
We study the spin dynamics in charged quantum dots in the situation where the resident electron is coupled to only about 200 nuclear spins and where the electron spin splitting induced by the...

Coherence resonance near a Hopf bifurcation. (2005)
Khovanov, I. A., Henneberger, F., Ushakov, O. V., Wunsche, J. H.
We report on the observation of coherence resonance for a semiconductor laser with short optical feedback close to Hopf bifurcations. Noise-induced self-pulsations are documented by distinct...
Stimulated emission from the biexciton in a single quantum dot (2005)
Akimov, I. A., Andrews, J. T., Henneberger, F.
Using two optical pulses of different frequencies, we demonstrate entanglement and disentanglement of the electronic states in Stranski-Krastanov quantum dots. Resonant two-photon excitation of the...
Synchronization of delay-coupled oscillators: A study of semiconductor lasers (2005)
Bauer, S., Kreissl, J., Ushakov, O., Korneyev, N., Henneberger, F., ...
Two delay-coupled semiconductor lasers are studied in the regime where the coupling delay is comparable to the time scales of the internal laser oscillations. Detuning the optical frequency between...
Nonlinear dynamics of semiconductor-lasers with active optical feedback (2004)
Bauer, S., Brox, O., Kreissl, J., Sartorius, B., Radziunas, M., Sieber, J., ...
An in-depth theoretical as well as experimental analysis of the nonlinear dynamics in semiconductor lasers with active optical feedback is presented. Use of a monolithically integrated multisection...
Self-organization in semiconductor lasers with ultrashort optical feedback (2004)
Ushakov, O., Bauer, S., Brox, O., Wünsche, H.J., Henneberger, F.
The dynamical behavior of a single-mode laser subject to optical feedback is investigated in the limit, when the delay time is much shorter than the period of the relaxation oscillations. Use of an...

Travniko, V. V., Kaibyshev, V. H., Rabe, M., Henneberger, F.
The presented paper investigated in detail the structure and intensity of resonant exciton-phonon (REP) spectra in ZnCdSe/ZnSe QW structures as functions of tunable laser energy at 8 K. We have found...
Excitability of a semiconductor laser by a two-mode homoclinic bifurcation (2002)
Wünsche, H.J., Brox, O., Radziunas, M., Henneberger, F.
We report on the preparation of optical excitability in a distributed feedback semiconductor laser. The device integrates a single-mode laser and a 250 ?m long passive section with cleaved facet. The...
Wruck, D., Boyn, R., Wienecke, M., Henneberger, F., Troppenz, U., Hüttl, B., ...
X-ray absorption fine structure and photoluminescence measurements are combined to analyze the structure of Cu centers in SrS:Cu thin-film and powder samples. We find that all the data can be...
Binding Energy of Charged Excitons in ZnSe-based Quantum Wells (2001)
