Controlling with light the amplitude and the direction of the deformation of a material
Thanks to the integration and characterization of ferroelectric thin films into capacitive micro-devices, a team of researchers at C2N has shown that it is possible to control their photostrictive response with a sub-nanosecond time resolution by playing on the …

Experimental demonstration of an on-chip, passive high-rejection filter in silicon
Physicists at C2N and Institut de Physique de Nice have found a simple and generic strategy to overcome one of the major limitations in the fabrication of on-chip filters. They experimentally demonstrated an optical rejection exceeding 80 dB, without …

Confined nanoscale sound controls light in a microresonator
Researchers demonstrate a semiconductor device for the tailored generation of Brillouin signals in the ultrahigh 100GHz-THz regime. When traversing a solid material such as glass, a light wave can deposit part of its energy in a mechanical wave, …

Macroscopic electron quantum coherence in a solid-state circuit
A team of researchers of C2N achieved in an experimental work a coherent propagation of electrons in circuits over macroscopic distances through a novel nano-engineering strategy. The quantum coherence of electronic quasiparticles underpins many of the emerging transport …

Taking advantage of disorder to trap sound and light
News from Institut de physique (INP) of CNRS - April 29, 2019 (released in French) Physicists have proposed a novel approach to confine light and sound waves at the same place using an approximately periodic nanoscale stack of …
