We show how topology optimization with a novel parameterization enables ultra-compact, robust, and broadband couplers for photonic wire bonds. A step toward fully exploiting 3D nanoprinting for photonics integration!! 💡🧪 Thanks to @cluster3dmm2o.bsky.social for support! doi.org/10.1109/JLT....

Our work on a multi-objective inverse design approach for 3D nanoprinting was published (doi.org/10.1515/nano...)! We combine a Maxwell solver with heat diffusion to ensure performance and fabrication feasibility of 3D free-form photonic devices. Thanks to 
@cluster3dmm2o.bsky.social for support!

We demonstrate multiphoton quantum interference in an ultracompact, topology-optimized tritter (8.0×4.5 µm²). We show that high-performance quantum photonic circuits can be small and scalable. Joint work of @cluster3dmm2o.bsky.social + @unistuttgart.bsky.social out here: arxiv.org/abs/2504.00114

Our Cluster PI @crockstuhl.bsky.social from @kit.edu just presented innovative methods for inverse design of 3D printed photonic devices. His work sets new standards in the control of light propagation for various advanced applications.🚀 #Photonics #3DPrinting #ClusterConference #3DMM2O

🚀🔭 Detecting gravitational waves in an undergrad lab? Unfortunately, not yet. However, analogy experiments can be done so students can explore many involved phenomena. Our new experiment teaches how matched filtering uncovers weak signals—just like LIGO! [https://doi.org/10.1119/5.0219962]

thanks to @solalpirelli.bsky.social for this nice piece on pseudoscience published by IEEE - and the need for the publisher to step up to the plate and start retracting this garbage if they want to retain any credibility. deevybee.blogspot.com/2025/02/ieee...

Bei der Bundestagswahl geht es um viel: nicht weniger als die Zukunftschancen unserer Kinder & Enkel. Die Welt ist in einem Wettlauf gegen die Zeit, eine katastrophale 3-Grad-Welt zu verhindern. Was auf dem Spiel steht hier nochmal kurz aus erster Forscherhand erklärt. ▶️ youtu.be/M6NWcKb5QBs?...

Some impressions from a lovely trip to the outskirts of Potsdam!

It's always great to witness a successful graduation, and somewhat sad at the same time to see them leaving. All the best, Mitchell, for whatever comes in your future! Kudos to you, and thanks for all the time we shared.

On my way across the optics and photonics landscape in Bordeaux! 💡

The bunch of marvelous people working on theoretical and computational nanophotonics at KIT. Taken at our retreat last week. So proud of each of them. 💡

Group retreat 2023 is in full swing.

Group picture with the fantastic #Photonics students, with whom we had a seminar on scientific writing co-organized by @optica.bsky.social and @opticapubsgroup.bsky.social. Great to discuss with the students many issues around publishing an article from the perspective of an author and editor.💡

Autumn doesn't look that bad from a #Photonics perspective (and as long as you are inside 😆). Beautiful colors everywhere (in reality, maybe more impressive) 💡.

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

It was super nice to discuss Optics Letters issues, and many other things, with Miguel in Marseille.
