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, ...

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 ...

From the growth to the fabrication and characterisation of oxide-based photonic devices

Thanks to material and photonic scientists, two groups from C2N have demonstrated the potential of Yttria-Stabilized Zirconia (YSZ) oxide for photonic applications. Despite the great progress achieved in silicon photonics the last decade, devices functionalities are still limited ...
