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. www.nature.com/articles/s41...

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...

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. 🤪 @attilio-zilli.bsky.social

📣📣📣 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...😅

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

Congratulations to the newly elected 🗳️ members of the Presidential Board of the Italian optical society (SIOF): Ilaria Rea, Roberto Rella, Maria Grazia Manera, Michele Celebrano @vynisle.bsky.social, Francesca Rossi, Andrea Cusano, Silvia Soria, Pietro Gucciardi, Tommaso Ongarello, Isabella Carrer.

📢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 arxiv.org/abs/2412.03422

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.

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.

I introduce you to the Origami laser we have been using for almost 10 years. Probably more than 30 papers, 2 Nat. Nano. NKT won't fix it. Luckily, we have a master of the cavities here at the Physics Department. Kudos to Nicola Coluccelli. Mode-locked and better mode than before!

Well, I guess I am back and here to stay. Food & wine lover. Light-matter interaction (especially nonlinear) is my passion... still not giving up on volley.

Being out for a while... Merry Christmas. It appears that I have now 5 more codes! @mickeykats.bsky.social @oradr.bsky.social if you need them I can send, but I have heard the recruitment is hard recently...

I was really tempted to play this flipper, but the currency did not allow it...😅 Well, since we are in Italy, I decided to cope with the disappointment with a pizza!

Hey @bsky.app community, it just popped up in my head. How we should call a post here? Is Tweet banned here? Suggestions?

Total blackout here... but the beauty of the stars in the sky compensate! I did not see anything like this since Australia. There are many more but the phone camera is not a single photon detector like our eyes! 😉 Photonics post of the evening...

Let's also welcome to the photonics community on @bsky.app Marco @marcoornigotti.bsky.social. I'm proud of my first well-spended code! He has just published on @optica.bsky.social an intriguing paper on accelerating waves!!! www.tuni.fi/en/news/acce...

Welcome @acalalesina.bsky.social with a very nice new paper, too! pubs.acs.org/doi/10.1021/... One thing I would like to do on Bluesky is to start advertising mostly other works and not only myself! 😅

Welcome to #photonics Bluesky @acalalesina.bsky.social !💡

Any help from more relevant people than myself?

Anyone know what a reference for a IEEE Senior Member looks like? I.e., what does the webpage ask for? Is it a proper letter to be uploaded via pdf, or just some text box? I can't find the information on the website

Today two great talks. Luigi Bonacina on in depth and fast Nonlinear imaging with nanoparticles. Then, a huge talk by Andrea Cavalleri on triggering superconductivity in YBCO with light!!! Awesome day.
