Source of correlated photons made (very) small!

Teams at Thales and C2N (CNRS/UPSaclay/UParis) have developed a novel miniaturized source of light called Photonic Crystal Optical Parametric Oscillator. An Optical Parametric Oscillator (OPO) is similar to a laser in that it generates coherent light, namely photons ...

On-Chip Mid-Infrared Supercontinuum Generation from 3 to 13 μm Wavelength

Mid-infrared spectroscopy is a universal way to identify chemical and biological substances. Indeed, when interacting with a light beam, most molecules are responsible for absorption at specific wavelengths in ...

Slow propagation of 2 GHz acoustical waves in a suspended GaAs phononic waveguide on insulator

A team of researchers at C2N have demonstrated slow propagation of acoustical waves in the ultra high frequency regime (UHF) through a suspended GaAs phononic waveguide. The experimental demonstration of a group velocity below 1000 m/s can ...

A Plug-and-play approach to integrated nanoacoustics

From taut strings vibrating in musical instruments to micro electro-mechanical systems for optoelectronics, vibrations cover an extensive range of applications. While at a macroscopic scale we are very familiar with ...
