Chiral transport of hot carriers in graphene in the quantum Hall regime
Bin Cao, Tobias Grass, Olivier Gazzano +12
Photocurrent (PC) measurements can reveal the relaxation dynamics of photo-excited hot carriers beyond the linear response of conventional transport experiments, a regime important…
Filter-free single-photon quantum dot resonance fluorescence in an integrated cavity-waveguide device
Tobias Huber, Marcelo Davanço, Markus Müller +3
Semiconductor quantum dots embedded in micro-pillar cavities are excellent emitters of single photons when pumped resonantly. Often, the same spatial mode is used to both resonantl…
Observation of chiral photocurrent transport in the quantum Hall regime in graphene
Olivier Gazzano, Bin Cao, Jiuning Hu +6
Optical excitation provides a powerful tool to investigate non-equilibrium physics in quantum Hall systems. Moreover, the length scale associated with photo-excited charge carries…
Quantum dot resonant-fluorescence linewidth narrowing and enhanced intensity
O. Gazzano, T. Huber, V. Loo +3
We study the processes in a quantum dot and its surrounds under resonant excitation with the addition of weak non-resonant light. We observe a decrease in inhomogeneous emission li…
Simultaneous, full characterization of a single-photon state using semiconductor quantum-dot light
Tim Thomay, Sergey V. Polyakov, Olivier Gazzano +3
As single-photon sources become more mature and are used more often in quantum information, communications and measurement applications, their characterization becomes more importa…
Highly Sensitive On-Chip Magnetometer with Saturable Absorbers in Two-Color Microcavities
O. Gazzano, C. Becher
Interacting resonators can lead to strong non-linearities but the details can be complicated to predict. In this work, we study the non-linearities introduced by two nested microca…
Scalable performance in solid-state single-photon sources
J. C. Loredo, N. A. Zakaria, N. Somaschi +13
The desiderata for an ideal photon source are high brightness, high single-photon purity, and high indistinguishability. Defining brightness at the first collection lens, these pro…
Probing the dynamics of a nuclear spin bath in diamond through time-resolved central spin magnetometry
A. Dréau, P. Jamonneau, O. Gazzano +4
Using fast electron spin resonance spectroscopy of a single nitrogen-vacancy defect in diamond, we demonstrate real-time readout of the Overhauser field produced by its nuclear spi…
An entangling quantum-logic gate operated with an ultrabright single photon-source
O. Gazzano, M. P. Almeida, A. K. Nowak +5
We demonstrate unambiguous entangling operation of a photonic quantum-logic gate driven by an ultrabright solid-state single-photon source. Indistinguishable single photons emitted…
Optical nonlinearity for few-photon pulses on a quantum dot-pillar cavity device
Vivien Loo, Christophe Arnold, Olivier Gazzano +6
Giant optical nonlinearity is observed under both continuous-wave and pulsed excitation in a deterministically-coupled quantum dot-micropillar system, in a pronounced strong-coupli…
Full control of spontaneous emission in confined Tamm plasmon structures
O. Gazzano, S. Michaelis de Vasconcellos, K. Gauthron +6
We demonstrate strong confinement of the optical field by depositing a micron sized metallic disk on a planar interferential mirror. Zero dimensional Tamm plasmon modes are evidenc…
