It was an absolute highlight to provide the theory for this impressive experiment. We used a multi-physics approach to model each step of the experiment from real-time TDDFT to surface hopping and coupled-cluster theory. We extract not just spectral data about geometry changes and electronic character, but also resolve the creation and dephasing of electronic and nuclear quantum beats – the inherent characteristics of coherent superpositions of molecular eigenstates. Work done during my time at Max Planck School of Photonics, Friedrich Schiller University Jena. #chemistry #attosecondscience #physics

🥁 New paper out on Arxiv demonstrating plug-and-play coherent detectors at 500 GHz, an envisioned terahertz communication band, on thin film lithium niobate platform. 🤓 🥳 👉 https://lnkd.in/ediYbXRA Once again the low loss and large transparency window of thin film lithium niobate platform is a key asset to enable integration of a two-dimensional array of terahertz antennas with the photonic circuit to conceptualize, implement and demonstrate selectivity to this desired band through a novel type of quasi-phase matching and robustness to illumination which is essential in out-of-lab scenarios. What's also fun is that we find that the antennas can act as pixels to aid reconstruct the THz beam profile at the chip. The results are obtained in a close collaboration with Harvard University. Congratulations to the HYLAB and Harvard team for making this happen! Alessandro Tomasino Amirhassan Shams-Ansari Marko Loncar

Me talking about the size of the upcoming January issue of Photonics Spectra.

Discover CINT Science — Current approaches to creating specifically polarized pairs of modes force a trade-off between maintaining high 𝑄 factors and robustness. In this research, a team of CINT Scientists led by Chloe F. Doiron solves this challenge by employing pairwise generation, annihilation, and positioning of polarization singularities, derived from symmetry-guaranteed pairs of symmetry-protected bound states in the continuum. Their approach opens new avenues for enhancing metasurface performance across a diverse range of applications, including sensing, modulating, nonlinear mixing, and generating quantum light. https://lnkd.in/gHQsCyHr

Hi guys the topic of this week is the extension of our previous report on application of photonics . Do give it a read.

Conversation with Dominique Bonnisseau, PhD, an expert in optics and photonics, about the challenges of quality control in the optical industry. He shares feedback from manufacturers on automated quality control solutions for optical components. And he gives his point of view on the innovations brought by V-OPTICS.   Don't miss this insightful exchange and find the link below (in the comments) to read the full article ⤵️

Great article about the power of nanophotonic biosensors, similar to the ones we are developing for biofilm detection at Phorest. https://lnkd.in/eRzdSNTN

Through collaboration with the National Research Council Canada / Conseil national de recherches Canada, Val Zwiller at KTH in Sweden, Klaus Jöns at Paderborn University, and Andreas Fognini at Single Quantum, we have developed a new way to generate nearly perfect entangled photons by semiconductor quantum dots in nanowires for secure communication. The key here was that we also considered the detection system in addition to how you excite the quantum dot to generate the entangled photon pairs. We also developed a new way to generate a secure key for quantum communication that is agnostic to an entangled state that oscillates in time. This oscillation of the quantum state was believed not to be useful for secure quantum communication but my colleagues at IQC showed that it is.
