Polariton condensates break a speed record
News (in French) from Institut de Physique (INP) of CNRS - 11 March 2019 Polaritons are half-light, half-matter, bosonic quasi-particules that are able to condensate in a single quantum state. For the first time, these usually quasi-immobile assemblies …

Linear electro-optic effect in a centrosymmetric semiconductor
Researchers from C2N demonstrated a high-speed Pockels effect in strained silicon waveguides, clearing the doubts raised over the last decade on its existence. The explosion of data demand imposed new requirements in terms of data transmission rate and …

First laser effect observed in germanium direct bandgap
A collaboration of researchers from C2N and STMicroelectronics has obtained, for the first time, a laser effect with germanium as active material thanks to direct alignment of the electronic band diagram. Until now, this material was known to be …

Taming sound at the nanoscale
Physicists have proposed a new way to control the propagation of sound at the nanoscale. They put in evidence new ways of trapping sound at the interface between two chains of nano-resonators. Topology offers new degrees of freedom …
