PROJECT DETAILS:

MPB Communications (MPBC) seeks to develop new laser components and single-frequency fiber laser systems for emerging quantum technologies, including quantum information processing, in order to address existing gaps in the market. The proposed lasers will operate at wavelengths required by the scientific community, notably around 813 nm. These new near-infrared laser sources will support the development of advanced applications in metrology and spectroscopy.

Ultra-long fiber Bragg grating reflectors (ULFBGRs) will play a central role in enabling high-power, single-frequency fiber lasers, which are critical for these applications. Achieving these previously unavailable wavelengths requires precise engineering of the laser structure, particularly the Bragg grating. Within this joint R&D project, MPBC will collaborate with Professor Kashyap’s research group at Polytechnique Montréal, which is internationally recognized for its expertise in the design and fabrication of ULFBGR devices. These devices will be further optimized and developed as part of the project.

The first phase of the project will focus on the design of ULFBGR devices and laser systems, the fabrication of prototypes, and the assessment of their performance and reliability. The second phase will address detailed characterization and the development of a robust packaging solution to ensure commercial viability. This phase may also lead to significant improvements in laser performance through enhanced thermal control of the laser cavity.
