A new Canada Research Chair at the ÉTS
Developing advanced modulation devices for terahertz (THz) wavesWednesday, January 27, 2021
François Blanchard, a professor in the Department of Electrical Engineering, is the new Canada Research Chair in Spatiotemporal Encryption of Terahertz Light Assisted by Computational Method. His work will aim to develop methods and technologies that will eventually make it possible to encrypt data transmitted by future ultra-wideband (UWB) telecommunications networks.
There are currently more than 25 billion connected objects on the planet. And that’s just the beginning: experts predict that the Internet of Things (IoT) market will continue to grow and increase by 8% by 2022. In addition to this unparalleled growth, there will also be an increase in global traffic on telecommunications networks, which will be seven times higher in 2021 than it was in 2016.
To perform well in such a context, these billions of connected objects will have to rely on reliable, secure and ultra-fast telecommunications networks. In addition, they will also have to consume less energy to contribute to the reduction of greenhouse gases (GHGs). From a technological standpoint, this is a duality since speed normally requires more energy.
“The use of terahertz radiation for electromagnetic frequencies ranging from 100 GHz to 10 THz could be part of the solution,” explains the new research chair. The terahertz segment of the electromagnetic spectrum offers significant bandwidths in an unencumbered part of the electromagnetic spectrum. These waves would also be ideally suited to the needs of short-range data transmissions requiring ultra-wideband (UWB) technologies, such as proximity radar and real-time medical imaging.
Professor Blanchard’s research program will focus on the development of new THz modulators using optical systems, metamaterials and micro-electromechanics for the development of encrypted communication systems and the reconstruction of images in this frequency range.
About the Canada Research Chairs Program
The Canada Research Chair in Spatiotemporal Encryption of Terahertz Light Assisted by Computational Method, which is a Tier 2 Chair, has received financial support from the Canada Foundation for Innovation (CFI). Tier 2 Canada Research Chairs are intended to recognize the work of outstanding researchers recognized by their peers as having the potential to become leaders in their field.
