Merry Christmas Season from the Smart Photonics Research Group in Jena @leibnizipht.bsky.social This beautiful speckle Christmas sphere was measured by our Master student Yuze Wu. Would love to have one of those on my tree in real. 🎄

Giant finger or tiny chip. Let's see what computes better. Exciting times ahead. ✨🤩✨

“…Quantum computing, a field that we rather see as a variant of digital computing and do not further address…” [since this decade is over]. Bold but gold. 🥇

Just on my way back from the International School of Physical Computing in the beautiful city Erice (IT). A fantastic event organized by Birgit Stiller, Antonio Cala Lesina and Wolfram Pernice. We definitely forged some future there. Looking forward for the upcoming events. 🙏

An absolutely correct move. But how to stop the ego-parade in Silicon Valley?!

„Today, Germany is in urgent need of change. Instead it’s getting Mr. Merz: yesterday’s man, with yesterday’s ideas.“ www.nytimes.com/2025/03/04/o...

Found in the middle of rural Germany: „Peace is the masterpiece of reason.“ Immanuel Kant

The ancient German satire Magazine Simplicissimus with 1907th hot topic „The Russian Dragon“ („Der russische Drache“). Very up-to-Date again.

Time for new innovations. www.telegraph.co.uk/business/202...

Me every time I hear one of the large laundry machine business guys talking about being close to artificial general intelligence. Let’s face it: LLM scaling is over. Research is needed. Into new models and fundamentally new hardware approaches. The future is light. 💡

Just accepted: Programmable Liquid-core fibers. Our breakthrough of 10 years of technological development together with my friend and mentor Prof. Markus Schmidt at the @leibnizipht.bsky.social Stay tuned 🚀

Claude, GPT-5 and a german AI meet in a bar. The barkeeper asks „How is it going?“ Claude: Thinking for 5 min. “It’s such a complex question! I’m good. Thanks.” GPT-5: “Status: Operational. Query processing at 99.7% efficiency. Next.” German AI: I am not authorize to give you this information.

Proud to see this article printed in this months issue of @spektrum.de Many thanks to Ms Menne and the editorial team for this great work. 🙏 Danke für die Gelegenheit.

Geniuses of our time…

So quantum madness ends, one article after the other. www.quantamagazine.org/teenager-fin...

I love Yann LeCun’s vibes. 😅

Just playing a bit with image generators. Love this one. ✨ Living the future ✨

The Smarties are on the way from CLEO Munich. What a great event! It was a pleasure.

Yay!! Today, we celebrated the first original paper from our Smart Photonics Group @leibnizipht.bsky.social. What a great success! Special guests: Bruno Pessoa Chaves, Manal Arbati from XLIM Limoges, and Andrei Ermolaev from Femto-ST Besançon, France. It was a very exciting exchange.

Meet us at #CLEO #Munich 2025. We have a series of exciting research insights prepared for you. From dispersion-programmable fibers to fundamentally new concepts of brain-inspired optical information processing. We look forward to seeing you there. Let’s bring out the #intelligence of #light. 🚀

Why is one part of society torturing themselves to report as truly and trustworthy as possible, just for not being believed by another part of society that has no problem with telling lies every minute?! 2025. The future.

@zdfde.bsky.social Wo sind eure guten Nachrichten heute?!

The three-year-old sings for themself into a tube “everyone is stupid”. Who am I to judge. 🥸

There are very few things that are universally true, but this one belongs to it: Regardless of who you are, where you come from, or what you believe in, if you break basic human rights, you are lawless and should be prosecuted.

A decade-long problem finally solved. Well done. 👍

If we limit global warming to +1.5°C, more than half of non-polar glaciers can be saved. This is the finding of an international collaborative study that calculated the potential ice loss of more than 200,000 glaciers: ethz.ch/en/news-and-...

🤣

Here the Administration lays the groundwork for weaponization of scientific principles to justify rollback of science-based policy actions. This isn't just hypothetical, its what the first-term Trump Administration and members of Congress have done for years. www.science.org/doi/10.1126/...

Here we go! This year’s “exam” for my ~20 students visiting my #Optical #MachineLearning lecture at the Friedrich-Schiller-University #Jena. The game is on. 🚀

France 🇫🇷 is on the run for AI leadership in Europe 🇪🇺 Very impressive! www.perplexity.ai/page/mgx-tea...

Paper alert! I am happy to share our recent study on nonlinear photonic neural networks in Nanophotonics! We explore the impact of optical chaos on optical computing with fibers. doi.org/10.1515/nano...

Einfach nur krass wie sich der Raab direkt ins Bild geschoben hat als es die 12 Punkte gab. Als hätte er das Lied gesungen. Wie schrecklich anmaßend! #janprixollivision

@janboehm.bsky.social Kommt Jungs! Baller. Wahrscheinlich der beste Song für Deutschland beim #ESC seit Jahren. #janprixollivision

Bisher ist Hazel auf Platz 1. Kommt da nochwas? #janprixollivision

Why should anybody in the world earn 100 Mio€ per year and not redistribute 90% of it into education and low-income families to stabilize society and keep earning in the future? I don’t understand.

It’s official. I’m Europe fanboy now. 🇪🇺 There is no future in #nationalism, #fascism, nor #oligarchy. Only in #unity!

The world's richest man has joined a growing chorus of right-wing voices attacking Wikipedia as part of an intensifying campaign against free and open access information. Why do they hate it so much?

My twisted friend #h-index, what do you like to tell me?! How many papers I publish and cross-reference? How big my network of friends is? How many people work in my community?! This is not important to me. The #innovation #potential of a paper is. This should be our #metric. Let’s measure it!

Two of my signature papers of 2023 are among the top-10% of the most viewed papers of Wiley journals LPR and Advanced Science. Aren’t those the small things that keep us going?! 🙏☺️

I just showed a friend how to look up The Keeling Curve's 800k graph and saw the 430 plus PPM. Holy Crap! Thanks, Eliot! keelingcurve.ucsd.edu

For those keeping track, Mauna Loa has just recorded three consecutive days with CO2 > 430 ppm. Reminder, the Climate Casino has set the over/under for peak monthly CO2 at Mauna Loa this year at 430.70 ppm. climatecasino.net/2024/12/wage...

Don’t look up. Part II.

Excited about this coverage of our work and the replication by @maxplanck.de with @lfoswaldo.bsky.social @lewan.bsky.social and Ralph Hertwig @arc-mpib.bsky.social www.mpg.de/24519906/dig...

A small fraction of a cubic millimeter of a mouse brain 👇 How dare we to think that any close to this complexity with any model we currently use for AI?! Complex natural phenomena may do it though. Once tamed.

Das ist Ah­med Mo­ha­med Odo­waa. Er ist einer der beiden Männer, die den Täter von Aschaffenburg verfolgt haben, bis die Polizei ihn festnehmen konnte. Dafür bekam er Dankesschreiben, von Söder und vom Innenministerium. Er muss Deutschland bis zum 8. Juli verlassen, sonst wird er abgeschoben.

#Spitzenforscher Jason Stanley zur Frage, ob er sich vorstellen könnte in Deutschland zu lehren:

Financial actions like this, alongside with freedom of speech and principals of equity, diversity, and inclusion, make #Europe 🇪🇺 the most fruitful environment to pursue world-leading #science to date. Thanks @ec.europa.eu 🇪🇺, thanks #Thüringen for investing in our labs. 🙏

🚨 Submission Deadline for #EOSAM2025 Extended! 🚨 Great news for all optics and photonics researchers, students, and professionals! The submission deadline has been extended, giving you more time to submit your abstracts for oral and poster presentations. 🔗 Submit here: www.conftool.com/eosam2025
