Neuromorphic computing with nanoscale spintronic oscillators
Neurons in the brain behave as nonlinear oscillators, which develop rhythmic activity and interact to process information. Taking inspiration from this behaviour to realize high-density, low-power neuromorphic computing will require very large numbers of nanoscale nonlinear oscillators. A simple …

Birth of electro-optical nanodiodes
Researchers from C2N, in collaboration with STMicroelectronics and Paris-Diderot University, have designed and manufactured silicon-based integrated laser nanodiodes that are able to transfer optical electrical information very efficiently within a chip. These resultsd have been published in Nature Photonics. …

Primary thermometry triad at 6 mK in mesoscopic circuits
Quantum physics emerge and develop as temperature is reduced. Although mesoscopic electrical circuits constitute an outstanding platform to explore quantum behaviour, the challenge in cooling the electrons impedes their potential. The strong coupling of such micrometre-scale devices with the …

Bi-periodic nanostructured waveguides for wavelength-selectivity of hybrid photonic devices
A bi-periodic nanostructuration consisting of a super-periodicity added to a nanohole lattice of sub-wavelength pitch is demonstrated to provide both modal confinement and wavelength selectivity within a hybrid III-V on Silicon waveguide. The wavelength selective behavior stems from finely-tuned …
