De l’électron au photon, le silicium fait sa (seconde) révolution

Laurent VIVIEN, Deputy Director of C2N and head of the Photonics Department, discusses the challenges of using silicon, a reference material in electronics, in an article published on the website The Conversation France. Today, silicon has also become a reference for the development of photonic integrated circuits, and can be used to meet the major challenges of numerous applications such as optical communications, sensors (chemical, gas and biological), near and mid-infrared optical spectroscopy, lidars, gyroscopes, quantum optics, and new-generation wireless networks (5G+, 6G, etc).

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 interact with the atom. Researchers at C2N, in collaboration with Institut Néel (Grenoble, France) have demonstrated the coherent control of an artificial atom with few photons. The quantum node …

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 …
