Linear electro-optic effect in a centrosymmetric semiconductor

Feb. 20, 2019 - Mathias Berciano

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

Dec. 14, 2018 - Moustafa El Kurdi

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 ...

Observing the growth of crystals in a transmission electron microscope

Oct. 30, 2018 - Jean-Christophe Harmand

A unique instrument has been developed to grow nanocrystals by molecular beam epitaxy in a transmission electron microscope. The crystal formation is observed in situ and in real time with the atomic resolution. Nanotechnology uses nano-sized crystalline materials ...

Coupled nano-oscillators capable of recognizing vowels according to a learning rule

Oct. 30, 2018 - Damien Querlioz

Physicists have succeeded in fabricating a network of four coupled nano-oscillators capable of recognizing spoken vowels by tuning their frequencies according to an automatic rule of real-time learning. They show that high experimental recognition rates are a result of ...
