PIATTAFORMA ECHENAIS PER LA DIDATTICA A DISTANZA E NON SOLO

posted Dec 18, 2020, 5:36 AM by Stefano Varas

Siamo lieti d'informare che la squadra coordinata dal nostro Collega Zeno Gaburro (UniTN) e costituita da Alessandro Chiasera (IFN-CNR) e Stefano Varas (IFN-CNR) ha creato una nuova piattaforma didattica per scuola, università e aziende, partendo da open source, storytelling e gamification. Sarà utilizzata in un corso di fisica per l'ingegneria di nuova impostazione, e la estenderemo alla scuola e alle aziende nel 2021.

Abstract
Optical sensing, taking advantage of the variety of available optical structures, is a rapidly expanding area. Over recent years, whispering gallery mode resonators, photonic crystals, optical waveguides, optical fibers and surface plasmon resonance have been exploited to devise different optical sensing configurations. In the present seminar we will discuss the state of the art of optical sensing devices based on 3D photonic crystals (PhCs) coupled to responsive materials. In the specific we will focus the attention on different PhCs, with particular reference to our own results in the field of mechanochromic sensors, where any physical phenomenon which affects the periodicity and the refractive index of the PhC structure induces changes in the intensity and spectral characteristics of the reflected, transmitted or diffracted light. Optical measurements allow one to sense, for instance, temperature, pressure, strain, chemical parameters, like pH and ionic strength, and the presence of chemical or biological elements. We believe that PhC sensors based on changes of structural color and mechanochromic effect are able to provide a promising, technologically simple, low-cost platform for further developing devices and functionalities.

Alessandro Chiasera will present one of the research topics of our Unit at FBK-CMM
"RF-sputtering fabrication of glass-based systems for flexible photonics"

Abstract
In this lecture we present some results concerning the fabrication of novel flexible optical layers by radio frequency sputtering deposition techniques. In particular, 1D photonic crystals and planar waveguides will be discussed both passive and activated by rare earth ions. The general idea is to develop a viable technological way to transform intrinsically rigid or brittle materials into highly mechanically flexible and optically functional systems.

"Solid-state dewetting of Si(Ge)-based complex nano-architectures and their applications in photonics and bio/chemical sensing"

Abstract
Silicon-based nanocrystals represent a promising resource both for next generation electronic devices and for nano-photonics applications but require precise size, shape and position control. However, owing to their large surface-area-to-volume ratio, thin semiconductor solid films are often unstable upon annealing. Under the action of surface diffusion, the film breaks eventually forming isolated islands. This is one of the main factors impeding the use of ultra-thin silicon films on insulators (UT-SOI) for the further miniaturization of electronic components. Today we propose to exploit the natural instability of thin solid films (solid state dewetting of silicon and germanium) to form complex patterns and nano-architectures (e.g. monocrystalline atomically-smooth structures, disordered hyperuniform metamaterials) that cannot be implemented with conventional methods. These patterns are used as: i) epitaxial platforms for the growth of light-emitting III-V compounds; ii) hard-masters for nano-imprint lithography of metal oxides (e.g. TiO) deposited via sol-gel dip-coating (soft-NIL) and printed on arbitrary substrates, with tunable chemical and physical properties (e.g. composition, porosity, wettability). Methods and structures are optimized towards their exploitation in two main domains of application: 1) photonic devices (e.g. anti-reflection coatings, colour-filters, random lasers, quantum emitters) and 2) micro-fluidic devices for bio/chemical sensing and water filtering. The research activity is performed in the framework of the EU H2020 FET-OPEN NARCISO (Grant No. 828890)
