Observation of the transition from lasing driven by a bosonic to a fermionic reservoir in a GaAs quantum well microcavity
S. Brodbeck, H. Suchomel, M. Amthor +4
We show that, by monitoring the free carrier reservoir in a GaAs-based quantum well microcavity under nonresonant pulsed optical pumping, lasing supported by a fermionic reservoir…
Single Semiconductor Quantum Dots in Microcavities: Bright sources of indistinguishable Photons
C. Schneider, P. Gold, C. -Y. Lu +3
In this chapter we will discuss the technology and experimental techniques to realize quantum dot (QD) single photon sources combining high outcoupling efficiencies and highest deg…
Hard X-ray photoemission spectroscopy of LaVO/SrTiO: Band alignment and electronic reconstruction
M. Stübinger, J. Gabel, P. Scheiderer +13
The heterostructure consisting of the Mott insulator LaVO and the band insulator SrTiO is considered a promising candidate for future photovoltaic applications. Not only do…
Broadband indistinguishability from bright parametric downconversion in a semiconductor waveguide
T. Günthner, B. Pressl, K. Laiho +5
Parametric downconversion (PDC) in semiconductor Bragg-reflection waveguides (BRW) is routinely exploited for photon-pair generation in the telecommunication range. Contrary to man…
Decay dynamics of quantum dots influenced by the local density of optical states of two-dimensional photonic crystal membranes
B. Julsgaard, J. Johansen, S. Stobbe +5
We have performed time-resolved spectroscopy on InAs quantum dot ensembles in photonic crystal membranes. The influence of the photonic crystal is investigated by varying the latti…
Temporally versatile polarization entanglement from Bragg-reflection waveguides
A. Schlager, B. Pressl, K. Laiho +5
Bragg-reflection waveguides emitting broadband parametric down-conversion (PDC) have been proven to be well suited for the on-chip generation of polarization entanglement in a stra…
