Silicon-germanium photo-receiver for mainstream telecom-waveband networks on a chip

Researchers at C2N, in co-operation with CEA LETI and STMicroelectronics, have demonstrated a power-efficient and high-speed silicon-germanium avalanche photo-receiver. The device is fully compatible with accessible semiconductor technology and fiber-optic links operated at telecom waveband standard. Owing to …

Mesoscopic limit cycles in coupled nanolasers under strong fluctuations

Using two coupled nanolasers, researchers have demonstrated the existence of limit cycles with only a thousand photons in the cavities, in spite of the strong spontaneous emission quantum noise influencing the system dynamics. Any freely decaying dissipative dynamical …

The cascade to criticality

Researchers at C2N (CNRS/Université Paris-Saclay), PhLAM laboratory (CNRS/Univ. de Lille) and ETH Zurich have unveiled a novel mechanism describing how criticality - a phase in which waves are neither extended nor localized but in a so-called “critical state” - …

Amplifying a weak signal by manipulating the nonlinear resonance in a nano-electromechanical resonator

A team of researchers at C2N has experimentally demonstrated an enhancement by more than an order of magnitude of a weak electrical signal thanks to nano-electromechanical resonator. Their results, supported by theory, illustrate a general mechanism which potentially applies …
