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…
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…
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 (…
Dynamics of excitons in individual InAs quantum dots revealed in four-wave mixing spectroscopy
Q. Mermillod, D. Wigger, V. Delmonte +8
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 o…
