Ongoing projects:

2019-2022 (Master Theses available). PRIN 2017: Nonlinear photonics in metal-less metasurfaces (NOMEN). 
The NOMEN project is about exploiting a new concept that has been recently introduced, first theoretically and then experimentally, namely the efficient use of second order nonlinear optics in metal-less nanoantennas and metasurfaces. The key idea is to demonstrate for the first time non-homogeneous all-dielectric metasurfaces for frequency conversion with complete tunable control of the spatial, polarization and frequency properties of the emitted photons exploiting second order nonlinear processes. This huge leap forward in the field will be a real breakthrough. Both classical and quantum frequency conversion processes driven by second order nonlinearities in all-dielectric metasurfaces will be addressed, since they offer many opportunities not yet exploited in several branches of basic and applied science. The project is coordinated by the University of Brescia in collaboration with: Prof. Michele Celebrano (Politecnico of Milano), Dott.ssa Monica Bollani (CNR-IFN), Prof. Lucio Andreani (University of Pavia).

 


2019-2021 (Master Theses available). CNR joint lab project (in collaboration with University Paris Diderot)Nonlinear photonics with metal-less nanoantennas and metasurfaces (OMEN)
The OMEN project capitalises on a newly developed scheme for enhanced second order optical nonlinearities to design, fabricate and test new classical and quantum platforms based on all-dielectric nanoantennas and metasurfaces. OMEN will fulfil its ambitious goals by engineering near and far field patterns of nanoantennas and by demonstrating all-dielectric metasurfaces featuring control over the spatial, polarization and frequency properties of the nonlinearly-generated photons. We intend to prove that in these dielectric metasurfaces sum and difference frequency generation and spontaneous parametric down conversion can all be efficiently achieved. OMEN is designed to establish a framework for our researchers to access both fabrication and characterization facilities in an integrated fashion, fostering new research activities that will in the end spur applications for nanoscale photonic devices.
