Integrated optoelectronics devices operating in the long wave infra red wavelength
Optical spectroscopy in the mid-infrared (mid-IR) range is an unambiguous way to detect environmental and toxic analytes. Therefore, mid-IR photonics has a great importance for many applications in sensing, imaging or even telecommunication. A challenging task is to make …

A Memristor-Based Bayesian Machine
Artificial intelligence is making major progress today, but it faces a challenge: its considerable energy consumption, which limits its applications and raises environmental issues. It is now well understood that this consumption comes from the separation, in computers, between …

Optical reading of multistate nonvolatile oxide memories based on the switchable ferroelectric photovoltaic effect
Researchers from C2N have developed a nonvolatile oxide memory device based on ferroelectric thin films showing eight stable and well-controlled information states. The information, stored in the remanent ferroelectric polarization of the material, can be written electrically by voltage …

Strong light-matter coupling observed with a nanoscale thermal transducer in a single nano-cavity
Researchers at C2N, in collaboration with University of Rome (Italy), Istituto Italiano di Technologia (Italy), Rice University (USA) and University Leeds (UK), have demonstrated an original nanospectroscopy technique that permits the study of the light−matter interaction in single subwavelength-sized …
