Generation of light in a photon-number quantum superposition
Physicists at C2N have demonstrated for the first time the direct generation of light in a state that is simultaneously a single photon, two photons, and no photon at all. They showed that the same kind of light emitters …

Ultrathin solar cells reach a record of nearly 20% efficiency
Researchers at the Centre de Nanosciences et de Nanotechnologies (C2N), in collaboration in particular with researchers at the German Fraunhofer ISE, have succeeded to trap sunlight efficiently in a solar cell thanks to an ultrathin absorbing layer made of …

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 …
