All-Dielectric Nanophotonic via Glass Fluid Instabilities

Pierre-Luc Eloi Piveteau

In this thesis work, we propose to exploit an innovative micro/nano-fabrication process, based on controlled fluid instabilities of a thin viscous film of chalcogenide glass. Amorphous selenium and arsenic triselenide were used in this thesis work, and com ...

Self-Assembled Dewetting as a Fabrication Platform for Photonics Applications

Bastien Schyrr, Fabien Sorin, Louis Marie Philippe Martin-Monier, Pierre-Luc Eloi Piveteau, William Nicolas Duncan Esposito

A novel fabrication method based on controlled fluid re-arrangement of thin amorphous optical glass film is leveraged to realize two large-area photonics metasurfaces: 1) a highly directional nanoantenna array (metareflector), and 2) a metagrating for inde ...

Controlled filamentation instability as a scalable fabrication approach to flexible metamaterials

Fabien Sorin, Louis Marie Philippe Martin-Monier, Pierre-Luc Eloi Piveteau, William Nicolas Duncan Esposito

Long and flexible arrays of nanowires find impactful applications in sensing, photonics, and energy harvesting. Conventional manufacturing relies largely on lithographic methods limited in wafer size, rigidity, and machine write time. Here, we report a sca ...

Novel insights into the design of stretchable electrical systems

Fabien Sorin, Louis Marie Philippe Martin-Monier, Pierre-Luc Eloi Piveteau

Soft electronics have recently gathered considerable interest because of their biomechanical compatibility. An important feature of deformable conductors is their electrical response to strain. While development of stretchable materials with high gauge fac ...

Prediction of Self-Assembled Dewetted Nanostructures for Photonics Applications via a Continuum-Mechanics Framework

François Gallaire, Fabien Sorin, Louis Marie Philippe Martin-Monier, Pier Giuseppe Ledda, Pierre-Luc Eloi Piveteau

When a liquid film lies on a nonwettable substrate, the configuration is unstable, and the film spontaneously ruptures to form droplets. This phenomenon, known as dewetting, commonly leads to undesirable morphological changes. Nevertheless, recent works, c ...
