Grant: Discovery Grants Program - Individual

The central objective of my research program is to explore new methods for the ultrasensitive detection of THz photons and the modulated information they carry. This will be done with the ultimate goal of reaching the detection limit of a single pair of photons, thus accessing the fascinating world of photonic quantum technology. This goal is especially important since, as of 2019, the THz band is considered the next wireless communications frontier to be reached for Beyond-5G and 6G networks; specifically, for the frequency range between 100 GHz and 3 THz. My proposed research program at ÉTS is primarily related to the use of infrared and THz photonic technologies for information technology. In the medium term, the development of key components based on affordable infrared technologies for modulation and detection of THz waves will be established, attracting industrial partners to this promising path. With this research program, the core technologies to be developed will not be limited to THz communication aspects, but will also have a substantial impact in advanced sensing, ultrafast infrared modulation, and conversion of THz information into optical information. This is a direct extension of my expertise, which aims at establishing systems and experimental procedures in the THz frequency range through the use of linear and nonlinear electro-optical materials assisted by innovative metasurface structures. Over the next five years, I will focus on two main areas related to THz waves: Improving ultrafast detection of THz information using near infrared (NIR) photons, and Developing new THz wave modulators and their modality to improve detection sensitivity. To be successful, I will progressively initiate each project to ensure that they are all undertaken using the same equipment, and only with minor modifications. In addition, my ongoing collaborations with Canadian university partners will be strengthened to successfully address some of the science that requires specialized expertise and instrumentation, thereby reducing the need for massive upfront investment while maximizing the results. In addition, my collaborations with local companies will be strengthened to facilitate technology transfer. Most importantly, this research will raise awareness of the potential of this exciting field and bridge the gap between the next generation of engineers and researchers who wish to be at the forefront of THz technologies.
