Efficient GHz electro-optical modulation with a nonlocal lithium niobate metasurface in the linear and nonlinear regime - Nature Communications A lithium niobate nonlocal metasurface with high-Q (~8000) resonances demonstrates efficient GHz-rate reflectivity modulation (~0.1) and one order of magnitude second harmonic modulation using sub-10V...

Just out our joint paper with UniBS and @ethz.ch on GHz speed modulation of linear and nonlinear light with a lithium niobate metasurface! Thanks @agostino.bsky.social @attilio-zilli.bsky.social @rachelgrange.bsky.social & the ETH team for this awesome collaboration.

The recent activity of our #Nano-optics Lab at #PoliMi (@vynisle.bsky.social, @paolobiagioni.bsky.social, and Marco Finazzi) is being showcased today at #PLASMONICA2025. Yaping Hou shows lithium niobate #metasurfaces for electro-optics. The enhancement of SHG by a qBIC was measured just few day ago!

Best PhD thesis (and cover) so far!!!

Rehearsal! Agostino tomorrow will defend his PhD on modulation and routing of nonlinear optical signals with metasurfaces!!!

20 years later, the same 2 guys graduating together are back together in a graduation committee! Time flies, but some things never change!

#Nanoplasmeta2025 comes to a close. 3 intense days in the amazing Porto! Great talks. Inspiring city. In random orders: edge detection, qBIC lecture, vortexes, Fourier gratings, optical analog commuting, on the origin of photoluminescence in gold, and much more!!! @paolobiagioni.bsky.social

Finally a hint of diversity in the group! A lot to celebrate:
- Chinese new year
- 3 new members
- 1 future member?
- 1 Nano-toddler coming soon
- 1 Keynote
- 1 new grant (stay tuned!)
Very excited!!
A lot of potential...I can only mess up now. 🤪

Committees - CLEO/Europe-EQEC 2025

📣📣📣 Only 4 days left to submit your latest research to #CLEO_EU! If you are working on #plasmonics and/or #metamaterials consider submitting at the EH Topical Session. www.cleoeurope.org/committees/

Final paper of the year submitted... now! 🫠
Happy New Year to everyone!!!

My camera was in M. Celebrano et al. mode...😅

Christmas lunch for the sNOm Lab...new people are joining and will join soon! Merry Christmas!!! Take your time off and relax!

Dealing with interference. The game started! Blue team against Red (Christmas) team. @attilio-zilli.bsky.social Alfonso and Agostino.

Let's go!

Looking forward to serve as best as I can the Italian photonic community! @plasmonica.bsky.social

Just to make sure... these days you never know. 😅

Of course I was sarcastic...😉

Remember, there is no such things as pandemics and global warming! 😱

Efficient GHz electro-optical modulation with a nonlocal lithium niobate metasurface in the linear and nonlinear regime Electro-optical modulation is widely employed for optical signal processing and in laser technology. To date, it is efficiently realized in integrated photonic systems as well as in bulk optics device...

📢Freshly packed by Agostino di Francescantonio. I hope this is a convincing step towards usable devices based on MS. This idea could have never been realized without the terrific expertise in the @ongeth.bsky.social group of @rachelgrange.bsky.social @ethzurich.bsky.social

It's officially Christmas time at the Physics Department at Politecnico di Milano, which, by the way, do not have yet and handle on #bluesky!!!

Anyway, I think we can all agree that we should put 'accepting to enter an editorial board on the 1st of December' in the top 10 worst decisions in science.

Let's start act professional here...🤐😉

I doubt I will desk-reject a paper from you 😶‍🌫️

Actually, I am the one getting a waiver for dealing with 60+ papers a year...😅

By the way, nice AI-based trolling!

Honestly, the things that most of all worries me is to bother colleagues with review requests.🫣

I prefer to think that I can give my contribution to select and disseminate only good science... and I won't enjoy all of them I am sure 😅

Yep! Fully aware...😅 Took me some time to decide.

Tomorrow, I officially start my new adventure as Associate Editor at Opt. Express! @optica.bsky.social
I am looking forward to receiving your solid research on nonlinear optics, nanophotonics and Metamaterials! opg.optica.org/content/jour...

New stand-up desk... first day test was great! It is probably the novelty but I like the idea of moving around while thinking and writing.

Absolutely. Especially nowadays that company do not have the same policy for assistance as before and certainly less excellent technicians.
