Exploring coherence of individual excitons in InAs quantum dots embedded in natural photonic defects: influence of the excitation intensity
Daniel Wigger, Valentin Delmonte, Quentin Mermillod +10
The exact optical response of quantum few-level systems depends crucially on the exact choice of the incoming pulse areas. We use four-wave mixing (FWM) spectroscopy to infer the c…
Antireflective photonic structure for coherent nonlinear spectroscopy of single magnetic quantum dots
W. Pacuski, J. -G. Rousset, V. Delmonte +6
This work presents epitaxial growth and optical spectroscopy of CdTe quantum dots (QDs) in (Cd,Zn,Mg)Te barriers placed on the top of (Cd,Zn,Mg)Te distributed Bragg reflector. The…
Coherent coupling of individual quantum dots measured with phase-referenced two-dimensional spectroscopy: photon echo versus double quantum coherence
Valentin Delmonte, Judith F. Specht, Tomasz Jakubczyk +7
We employ two-dimensional (2D) coherent, nonlinear spectroscopy to investigate couplings within individual InAs quantum dots (QD) and QD molecules. Swapping pulse ordering in a two…
Impact of phonons on dephasing of individual excitons in deterministic quantum dot microlenses
T. Jakubczyk, V. Delmonte, S. Fischbach +12
Optimized light-matter coupling in semiconductor nanostructures is a key to understand their optical properties and can be enabled by advanced fabrication techniques. Using in-situ…
Radiatively limited dephasing and exciton dynamics in MoSe monolayers
Tomasz Jakubczyk, Valentin Delmonte, Maciej Koperski +5
By implementing four-wave mixing (FWM) micro-spectroscopy we measure coherence and population dynamics of the exciton transitions in monolayers of MoSe. We reveal their dephasi…
Harvesting, coupling and control of single exciton coherences in photonic waveguide antennas
Q. Mermillod, T. Jakubczyk, V. Delmonte +5
We perform coherent non-linear spectroscopy of individual excitons strongly confined in single InAs quantum dots (QDs). The retrieval of their intrinsically weak four-wave mixing (…
