The university is closed due to the COVID9 emergency. However research and teaching activities continue online! See you soon!
SPDC and phase matching
We show that in a photonic crystal the SPDC generation rate can scale with the fifth power of the structure length despite phase-matching condition is not satisfied. This work is now published in Optics Letters.
Squeezing and CV quantum sampling
We propose a novel squeezed light source capable of meeting the stringent requirements of continuous variable quantum sampling. This work is now published in Physical Review Applied.
This week I am at Xanadu, a quantum photonic company with a terrific team of people working hard to develop photonic-based quantum computing.
Last week in Como, we had the kickoff meeting of NOMEN, a MIUR-funded project aiming at exploring the use of metal-less nanoantennas and metasurfaces to develop new platforms for nonlinear photonics applications.
Nonlinear coupling of two optical resonators
We have demonstrated nonlinear optical coupling of two linearly uncoupled integrated resonators. This work is now published in Optics Letters.
Dr. Corrado Sciancalepore of CEA-LETI (France) will be visiting the Department of Physics on November 4-5. He will give a seminar on "Ultra-low loss SiN Photonics" on Nov. 5 at 3.30 PM in Aula Dottorato.
Topological photonics in nonlinear optics
We demonstrated that topological protection of the linear properties of an optical system does not equally extend to the case of nonlinear interactions. This work is now published in Physical Review A.
Single-mode squeezing in an integrated device
Xanadu demonstrates the generation of broadband single-mode quadrature squeezed vacuum from an integrated nanophotonic device. This work is available on arXiv
Happy New Year
We wish you all the best for a joyful and productive 2020!
Luca has successfully defended his Master thesis on Friday, and he will join our group as PhD canditate starting immediately.
A field trip
Today we had our annual field trip for the grape harvest. A bit of work in the vineyard followed by a lot of pizzoccheri and other delicious food from Valtellina!
