Topological gap solitons in a 1D non-Hermitian lattice
N. Pernet, P. St-Jean, D. D. Solnyshkov +13
Nonlinear topological photonics is an emerging field aiming at extending the fascinating properties of topological states to the realm where interactions between the system constit…
Exchange interaction-driven dynamic nuclear polarization in Mn-doped InGaAs/GaAs quantum dots
O. Krebs, E. Baudin, A. Lemaître
We investigated optical spin orientation and dynamic nuclear polarization (DNP) in individual self-assembled InGaAs/GaAs quantum dots (QDs) doped by a single Mn atom, a magnetic im…
Realization of an all optical exciton-polariton router
Félix Marsault, Hai Son Nguyen, Dimitrii Tanese +5
We report on the experimental realization of an all optical router for exciton-polaritons. This device is based on the design proposed by H. Flayac and I.G. Savenko [APL 103, 20110…
Driven-dissipative confined polariton condensate under magnetic field
C. Sturm, D. Solnyshkov, O. Krebs +6
We investigate exciton-polariton condensation under magnetic field in a single high-quality semiconductor micropillar cavity. We observe successive polariton condensation of each s…
Vortex stability and permanent flow in nonequilibrium polariton condensates
G. Tosi, D. Sanvitto, M. Baudisch +6
We study the effects of imprinting a single-quantized vortex on the steady state of a microcavity exciton-polariton condensate generated via parametric scattering. Interestingly we…
Dynamic nuclear polarization in InGaAs/GaAs and GaAs/AlGaAs quantum dots under non-resonant ultra-low power optical excitation

We study experimentally the dependence of dynamic nuclear spin polarization on the power of non-resonant optical excitation in two types of individual neutral semiconductor quantum…
Realization of a double barrier resonant tunneling diode for cavity polaritons
Hai Son Nguyen, Dmitry Vishnevsky, Chris Sturm +8
We report on the realization of a double barrier resonant tunneling diode for cavity polaritons, by lateral patterning of a one-dimensional cavity. Sharp transmission resonances ar…
On-demand confinement of semiconductor excitons by all-optical control
M. Alloing, A. Lemaitre, E. Galopin +1
In condensed-matter physics, remarkable advances have been made with atomic systems by establishing a thorough control over cooling and trapping techniques. In semiconductors, this…
Non-linear dynamics and inner-ring photoluminescence pattern of indirect excitons
M. Alloing, A. Lemaitre, E. Galopin +1
We study the photoluminescence dynamics of ultra-cold indirect excitons optically created in a double quantum well heterostructure. Above a threshold laser excitation, our experime…
Spin precession and inverted Hanle effect in a semiconductor near a finite-roughness ferromagnetic interface
S. P. Dash, S. Sharma, J. C. Le Breton +5
Although the creation of spin polarization in various non-magnetic media via electrical spin injection from a ferromagnetic tunnel contact has been demonstrated, much of the basic…
Optically tunable nuclear magnetic resonance in a single quantum dot
M. N. Makhonin, E. A. Chekhovich, P. Senellart +3
We report optically detected nuclear magnetic resonance (ODNMR) measurements on small ensembles of nuclear spins in single GaAs quantum dots. Using ODNMR we make direct measurement…
