ENTENTE project : Laureate of the CNRS RISE programme

Rémy Braive and Giuseppe Modica, with the support of Robert Horvath, all three researchers at C2N, have developed a new technology for integrated frequency generators on a chip based on the concepts of optomechanics (interaction between optics and acoustics).
This innovative technology, by improving the precision of data arrival times, will revolutionise numerous applications such as the localisation of autonomous vehicles or cloud computing.
This research work led to the ENTENTE project, selected in the latest promotion of the CNRS RISE programme, which supports and creates start-ups from CNRS laboratories.

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 integrated circuits for microelectronics. This work was published in the journal Nanotechnology.

Near optimal single photon sources in the solid-state

Researchers at C2N, in collaboration with Institut Néel (Grenoble, France) and University of Queensland (Australia), have fabricated single photon sources based on semiconductor quantum dots of unprecedented quality. They succeeded in combining a unique technique invented in 2008 to position a quantum dot at the center of a micropillar acting as an optical cavity and an electrical control to remove the charge noise. They demonstrated the controlled …
