Getting memory directly involved in optimization computation: a new approach explored for solving complex problems

This is the major result of collaborative work carried out between CEA-Leti, SPINTEC, and C2N, which has just been published in Nature Communications. Instead of separating memory and processing as in conventional computers, the researchers combined two complementary nanotechnologies on a single component to create a new optimization processor (an Ising machine). What these results show: The voltage used to read the memory helps regulate …

Pulse generation by on-chip dispersion compensation at 8 μm wavelength

The mid-infrared spectral region holds growing importance for applications such as gas sensing and spectroscopy, and compact ultrashort pulse laser sources are essential to enable these applications. However, the fast gain dynamics of intersubband transitions hinders the direct generation of pulses from quantum cascade lasers (QCL). In this work, based on a collaboration between C2N (CNRS/Universite Paris Saclay), ETH Zurich and Politecnico di Milano, we take advantage of …
