CLEO 2025

| on 05 June 2025

In early May our team attended <a href=https://cleoconference.org/"> CLEO (Conference on Lasers and Electro-Optics) 2025 in Long Beach, California. CLEO created a dynamic setting to introduce our latest solutions, share insights, and engage with laser technology groups as well as the ultrafast & quantum optics community.

Conference Highlights:

In Good Company

We had the pleasure of being located right next to our friends from Thorlabs! The Thorlabs Quantum Edu Kit showcases the EDU version of our Time Tagger 20, providing a fantastic package for quantum research and education groups looking for a streamlined one-stop solution.

Exciting Research in the Field

It was great to get the chance to meet up with and learn more about the work of several researchers during the poster sessions, where our hardware played a supporting role in some compelling projects.

Bryan Turo (CREOL, University of Central Florida) presented work on shaping and analyzing non-local spacetime wavepackets generated via SPDC. It was great hearing more about how him and his team use the Time Tagger Ultra for coincidence and singles detection to characterize spatial-temporal correlations in signal and idler photons.

We learned more about Georgios Papangelakis’ (University of Toronto) work, and how they use the Time Tagger X to measure time-domain and FrFT-domain correlations of SPDC photon pairs. Their approach improves noise rejection with applications in quantum communications and LiDAR.

We caught up with Siyuan Zhang (Duke University), who shared recent work on tunable nanoscale sources for quantum photonics. His team used the Time Tagger X to explore SPDC in plasmonic nanocavities, including second-order correlation and lifetime measurements.

Live Demos

We had a great time running some hands-on demos at the booth, including our fluorescence lifetime (from a SPAD and pulsed laser source) and frequency stability measurements (to characterize an oscillator and obtain ADEV, MDEV, HDEV measurements in real-time!)

Our reaction game returns, once again proving that nothing brings out competitive spirit quite like measuring reaction times down to the picosecond! Labmates challenged each other, PIs were dragged in, and more than a few reputations were (gently) tested. Behind the fun was a simple reminder: precision timing doesn’t always have to feel like work :)

Introducing New Capabilities

We introduced the virtual channels Coincidences(), DelayedChannel(), and GatedChannel() are now available in our GUI for the first time! For many this marked an enabling next step, making advanced timing logic accessible without coding as experimental needs grow more complex.
