Two students in our group received their PhD at the convocation last weekend. They both built the Ultrafast THz lab from the ground up.
Congratulations Dr. Wei Cui and Dr. Nicolas Couture!
Furthermore, Nicolas received the 2023 Governor General’s Gold Medal for his thesis!
😆🥳
We efficiently trap light inside sugar to change its properties. Does this hybrid state have a better taste than good-old sugar? Not sure... but it will certainly have many applications in polaritonic chemistry! rdcu.be/dIWBs

ALT Sample architecture combining the concept of a planar optical cavity with a metasurface to trap THz light within a layer of glucose (sugar). The resulting hybrid state is a quantum superposition of light and a molecular vibration of glucose forming polaritons. https://www.nature.com/articles/s41467-024-48764-6
No time to waste? Use our rapid single-pulse THz system to monitor low-energy resonances in real time with a 20 µs resolution. Check out our Nature Comm: rdcu.be/dbr6O. Great collaboration with Angela Gamouras and @NickJolysLab.

Using polymer, some tape (yes tape!) and a bit of metal, we fabricate a metamaterial for high-performance THz spectral filtering. This work, in collaboration with @BoydNLOLAb and @IridianSpectral, was published today in Photonics Research @OSAPublishing

In this work, led by Jaewoo and involving an amazing team of undergrads, we wanted to see how far we can take graphene-based sensing technology and push it towards real-life applications. At the end we were flying gas sensors on a drone!

Our cover just got out in ACS Sensors. It shows UV LEDs enhancing performances of graphene-based gas sensors by changing the electrical interactions between graphene and three chemicals tested in our experiments. @CRPuO @uOttawaScience #MyACSCover

Our paper on grating-assisted THz generation and detection has been published！
onlinelibrary.wiley.com/doi/…
We present a stacked metasurface device with broad bandpass filtering properties in THz region. We demonstrate how we can use spectral filters to enhance the “signal to noise ratio”.

You might be wondering what happens when light is generated and modulated at the speed of light, or even faster. We did this experiment in collaboration with the group of Dave Cooke. In short, we see very cool stuff! We expand on that in this paper: nature.com/articles/s42005-0…
