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 ...

A microlaser emitting helical light

Researchers recently demonstrated the realization of an integrated microlaser based on a novel design that allows emitting light in chiral modes, thus producing corkscrews of light. An object is said to be chiral if it can be distinguished ...

Polariton condensates break a speed record

News (in French) from Institut de Physique (INP) of CNRS - 11 March 2019 Polaritons are half-light, half-matter, bosonic quasi-particules that are able to condensate in a single quantum state. For the first time, these usually quasi-immobile assemblies ...

Linear electro-optic effect in a centrosymmetric semiconductor

Researchers from C2N demonstrated a high-speed Pockels effect in strained silicon waveguides, clearing the doubts raised over the last decade on its existence. The explosion of data demand imposed new requirements in terms of data transmission rate and ...
