Exchange interaction-driven dynamic nuclear polarization in Mn-doped InGaAs/GaAs quantum dots
The optical spin orientation and subsequent dynamic nuclear polarization (DNP) in individual self-assembled InGaAs/GaAs quantum dots doped by a single Mn atom is shown to be strongly perturbed by the exchange interaction between a photo-created electron and the spin …

Flexible nitride nanowires light emitting diodes
Presently, flexible light sources mainly use organic materials integrated on lightweight and flexible plastic substrates. However, organic LEDs present a much lower luminance and a shorter lifetime in comparison to the LEDs based on inorganic nitride semiconductors. The inorganic …

Controlling carbon nanotube photoluminescence using silicon microring resonators
By depositing carbon nanotubes on ring-shaped micro-resonators, researchers at C2N (CNRS / Université Paris-Sud) managed to control the light emitted by the nanotubes. This technology could be optimized for future applications in optical telecommunications or …

Coherent control of an artificial atom with few photons
In an optical quantum network, the information is transferred from one node to an other through light. A possible building block for such quantum network is an atom in a cavity. Ideally, every photon sent on the node should …
