The Center focuses its research activities in strategic sectors of telecommunications, photonics and energy.
The Centre capitalize on its major research infrastructures, (over 40 million dollars have recently been granted, mainly by the Canadian Foundation for Innovation) and Québec’s Ministry of Education, for a unique infrastructure in Canada, and also benefits from significantly multidisciplinary character of its faculty. We are in the process of dramatically increasing its scientific and technological impact in key sectors of Québec’s economic development. In the area of telecommunications and photonics, our faculties work mainly in the following research directions:
This research area is devoted to the development of tools and “know-how” that are essential for the design and the deployment of future telecommunication networks. More specifically, we are dealing with the problems of Quality of Service (QoS), i.e. ensuring that new Internet applications attain the level of quality required for their proper operations. The study of network architectures and deployment, management and security aspects of networking services also constitute complementary research dimensions. Finally, we are investigating the basic framework of design and deployment of new telecommunication networks based on optical and/or wireless technologies.
This line of research is concentrated on the development of wireless communication systems. The professors in this area focus their respective research programs on data transmission at high speed and transmission of multimedia data where communication rates are in the order of 1 to 10 Mbps. The long term goals are to achieve the research ability required to successfully face the evolution of present-day wireless systems towards the so-called fourth generation, where the emphasis is on achieving solutions for the heavy loads implied by multimedia data transmission over wireless Internet.
MULTIMEDIA SIGNAL PROCESSING
With the collaboration of: Hesham Tolba (Invited Professor).
This area is dedicated to the resolution of major problems in speech recognition and synthesis as well as to the improvement of the performance of computer algorithms for speech – to – text conversion. Our objective is also to improve automatical speech synthesis, i.e. to improve the performance of computer algorithms for text – to – speech conversion. Part of our work is devoted to the numerical processing of sound signals, our main objective being to improve acquisition, codification and restitution. Our work on image processing is focused on two main subjects: (a) movement analysis and (b) handwritten script recognition.

With the collaboration of: de Henri Pépin (50%, Emeritus professor).
This research program is concentrated around three main themes of investigation:
- Optical sources and techniques for high-speed (femtosecond-scale) measurement.
- Molecular photonics with applications to structural dynamics in biology, condensed matter, telecommunications and medicine.
- Development of new photonic components, as well as their optical characterization and the synthesis of novel materials for optoelectronics.
Theoretical efforts are directed towards various aspects of high-speed photonics, nanotechnology, characterization (LIBS and ultrasound generation) and design of X-ray sources in the femtosecond regime (including the study of solid plasmas from which these sources are created).

ANALYSIS AND ENERGY MODELING (GAME)
With the participation of: Gaëtan Lafrance (Honorary professor)
We apply mathematics and engineering in the field of energy and electrical supply networks. In particular, the following research orientations are emphasized because of their importance for the future:
- Modeling of the demand and supply in the electrical sector: forecasting model, optimal strategies of electrification, technological perspectives.
- Wind power: the integration of large parks of wind mills in the existing electrical supply networks, estimation of wind resources by satellite.
- Energy-environment: impact of climatic changes for society, impact of environmental factors and the Kyoto protocol on supply and demand, risk analysis choice of energy sources.
MAGNETIC CONFINEMENT FUSION
With the collaboration of: Jean-Marc Larsen (20%, Honorary professor), Andranik Sarkissian (50%, %, Research Associate and President of Plasmionique) et Michel Trépanier (Professor at UCS Research Centre)
The main objective of our research is to maintain Quebec’s expertise acquired in thermonuclear fusion via established and potential international partnerships. We pursue activities in: computer simulation of plasma behavior and advanced diagnostics.
The computer plasma simulation efforts consist of:
- Contributions to the design of the prototype reactor for ITER fusion.
