Reference number : GC-2017-Q3-00842, amendment number : , agreement type : G, recipient legal name : Galstian, Tigran (Université Laval), recipient country : CA, recipient province : nan, recipient city : Quebec|Québec, recipient postal code : nan, program name english : Strategic Projects - Group, program name french : Projets stratégiques - groupe, program purpose english : The ATONAL project aims at developing micro- and nano-structured functional systems that can be optically_x000D_
tuned, by exploiting the photoswitching properties of materials containing photochromic molecules such as_x000D_
azobenzene derivatives. In recent years, new approaches have emerged, in the field of information and_x000D_
communication technologies, based on the development of micro- and nano-structured devices (for integrated_x000D_
optics, efficient light sources...) or on the use of innovative media and materials (flexible electronics, organic_x000D_
optoelectronic...)._x000D_
These approaches have been made possible by the technological developments that now allow matter_x000D_
processing down to ultimate scales and integration of different materials in a same architecture. In this context,_x000D_
the main objective of the ATONAL project is to investigate the potentiality of hybrid structures incorporating_x000D_
photochromic materials for the elaboration of optically tunable devices in biomedical applications._x000D_
Materials incorporating azobenzene derivatives exhibit quite unique photomechanical responses in addition to_x000D_
their photochromic properties. These deformations are directed by the light polarization and may manifest at_x000D_
different scales. Coupling these compounds with other functional materials may then be envisaged as a route_x000D_
for developing structures and devices that can be actuated, tuned or reconfigured by means of optical stimuli._x000D_
As a proof of concept, we will first develop simple processes to couple photoactive hybrid material layers with_x000D_
usual integrated optical devices (for telecommunication application), fabricated with standard silicon_x000D_
technologies. We will consider devices such as ring resonators, couplers, filters and gratings, the operation of_x000D_
which critically depends on their structure. We will then characterize the control of their functioning conferred_x000D_
by the photoactive material. Finally, in collaboration with the companies supporting the project, we will_x000D_
explore the possibility to implement this approach into real-world devices._x000D_, program purpose french : The ATONAL project aims at developing micro- and nano-structured functional systems that can be optically_x000D_
