A Plug-and-play approach to integrated nanoacoustics

Nov. 4, 2020 - Daniel Lanzilloti Kimura

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 ...

Ever thinner solar cells

Nov. 3, 2020 - Stéphane Collin

Thickness reduction can be a key element in the quest for cheaper and more efficient solar cells. Making solar cells at least 10 times thinner than commercial ones would save material, ...

Versatile Photonic Entanglement Synthesizer in the Spatial Domain

Oct. 15, 2020 - David Barral, Kamel Bencheikh, Juan Ariel Levenson, Nadia Beladas

Abstract Multimode entanglement is an essential resource for quantum information in continuous-variable systems. Light-based quantum technologies will arguably not be built upon table-top bulk setups, but will presumably rather resort to integrated optics. Sequential bulk opticslike proposals based on cascaded ...

Phase Transition in a Memristive Suspended MoS2 Monolayer Probed by Opto-and Electro-Mechanics

Oct. 15, 2020 - Julien Chaste, Imen Hnid, Lama Khalil, Alan Durnez, Xavier Lafosse, Abdelkarim Ouerghi

In recent years, new 2D semiconductor materials have shown exotic and exciting electronic or optoelectronic properties with multiple applications. In particular, several interesting mechanisms can hybridize in the same device. We have develop ...

Quantum state engineering in arrays of nonlinear waveguides

Oct. 13, 2020 - David Barral, Kamel Bencheikh, Juan Ariel Levenson, and Nadia Belabas

Abstract In the current quest for efficient and experimentally feasible platforms for implementation of multimode squeezing and entanglement in the continuous variable regime, we underpin and complement our results on the generation of versatile multimode ...
