Telecommunications

More than half a million dollars for space telecommunications research

Professor Rosei’s team is leading this project in collaboration with Polytechnique Montréal and Montreal companies Pi-SOL Technologies and MPB Communications.

“This partnership leverages the complementary expertise of each group to achieve our common goals of monitoring and optimizing innovative devices for applications in space,” said Professor Rosei, recipient of the Prix du Québec Marie-Victorin. 2021.

This multidisciplinary project will make it possible to further develop Québec expertise in telecommunications, advanced technologies and aerospace engineering. Improving the performance and extending the durability of fibers doped with erbium and ytterbium, two rare earths, will meet the needs of the aerospace industry.

“Our government’s support for research into innovative materials will enable the Québec aerospace sector to pursue its development and remain a leader in the technologies of the future,” declared Peter FitzgibbonMinister of Economy and Innovation and Minister responsible for Regional Economic Development.

Two phases of research

The team will first focus on optimizing a “photobleaching” process to regenerate fibers exposed to radiation. This process uses a laser source to restore the optical properties of the fibers. This first step will provide a better understanding of fiber-laser interactions and the effects of radiation on materials.

Secondly, the team will focus on converting the heat dissipated by the fibers into electrical energy. For this, the scientists will develop a thermoelectric coating to ensure optimal energy recovery.

This project will eventually make it possible to carry out very high-speed satellite communications as long as the fibers are used in space. This would allow scientists to receive Earth observation images in near real time.

About the project

The project, titled “Development of active high-power erbium and erbium-ytterbium doped optical fibers for ultra-fast telecommunications satellites” [Development of high-power active optical fibers doped with erbium and erbium-ytterbium for ultra-fast satellite communications]is funded by the Natural Sciences and Engineering Research Council of Canada (NSERC) and PRIMA Quebec.

About INRS

INRS is a university dedicated exclusively to research and graduate training. Since its creation in 1969, INRS has played an active role in the economic, social and cultural development of Quebec and ranks first for the intensity of research in Quebec. INRS is made up of four interdisciplinary research and training centers in Quebec City, Montreal, Lavaland Varennes, with expertise in strategic sectors: Water Land Environment, Energy Materials Telecommunications, Urbanization Culture Society and Armand-Frappier Health Biotechnology. The INRS community includes more than 1,500 students, postdoctoral fellows, faculty members and staff.
