Due to their narrow reflection peak as well as their compact structure, guided mode resonance filters (GMRFs) are attractive for many applications. In this work, we will demonstrate the possibility to modulate the properties of a GMRF by associating

Energy measurements of electrons emitted from a semiconductor can reveal internal physical processes hitherto elusive. Signatures of hot-electron processes in heterostructures have been observed from cesiated, light-emitting, and p-i-n diodes. In p-i

Light tunable azopolymers : Photomechanical phenomena and multifunctional materials

Autor: Zhao Chen, David Bouville, Y. Lassailly, Khalid Lahlil, Mario Fafard, Thierry Gacoin, Lucio Martinelli, Sylvain Chevalier, Olivier Lefebvre, Ahn DucVu, Luca Sorelli, Jessy Frech-Baronet, Jacques Peretti, Filippo Fabbri

Publikováno v: 2019 Photonics North (PN).

Light tunable materials such as azobenzene-containing polymers are nowadays a promising way to achieve optical control of matter up to the nanoscale. In particular, the materials’ optical and mechanical responses can be tuned by controlling the spa
