This research project is essential for solving a specific problem in electrical power transmission. Traditionally, this transmission is carried out using copper electrical connectors, but this can pose difficulties in certain situations, particularly when galvanic isolation is required to protect against lightning strikes, or in flammable or explosive environments. To overcome these obstacles, the idea of transporting electrical power optically has emerged. This concept involves the use of a light source, an optical transport medium such as an optical fiber, and an optoelectronic receiver. However, challenges remain in developing an efficient and effective system.

Optoelectronic devices are used in a wide range of applications, including telecommunications, sensors, imaging systems, lighting, and surveillance systems. This project aims to combine III-V semiconductor technologies (lasers and phototransducers) and develop new cleanroom manufacturing processes. The expected results include the manufacture of phototransducers operating at record voltages and the evaluation of the feasibility of integrating III-V lasers into a photonic circuit using a new assembly approach, with the aim of designing a high-voltage output optical power conversion system.

The technological advances achieved in this project will help position Quebec as a leader in the field of optical power conversion, thereby stimulating innovation and economic growth.
