Genetic optimization of Brillouin scattering gain in subwavelength-structured silicon membrane waveguides
On-chip Brillouin optomechanics has great potential for applications in communications, sensing, and quantum technologies. Tight confinement of near-infrared photons and gigahertz phonons in integrated waveguides remains a key challenge to achieving strong on-chip Brillouin gain. Here, we propose a …

Subwavelength Control of Photons and Phonons in Release-Free Silicon Optomechanical Resonators
Integrated optomechanics finds increasingly broadening applications, requiring tight confinement of photons and phonons within nanometric-scale photonic circuits. However, most existing integrated optomechanical devices use unconventional materials or suspended structures that hinder co-integration with scalable photonic technologies. Here, we show …

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 …
