Coordinator : Stéphane Trebaol
The SP Department conducts research in the field of laser physics and its applications. The architectures investigated include fiber lasers, semiconductor lasers, and optical microcavities, with applications ranging from optical functions for sensing systems to optical communications, a field in which the department has established strong international recognition. The research activities are primarily experimental and cover topics ranging from fundamental studies, such as laser noise analysis and nonlinear optical phenomena, to very high-speed optical communication system demonstrations. In addition, several members of the department pursue more theoretical research based on analytical modeling approaches.

Laser Physics and Applications (PLA)
Research within the Laser Physics and Applications (PLA) theme focuses on the physics and applications of light sources, including fiber lasers, semiconductor lasers, and optical microcavities. The main targeted applications are optical functions for optical communications and optical sensing. Research activities in this area rely on materials and structures developed by academic laboratories (including the OHM Department), industrial partners, and international collaborators.
Research activities within the PLA theme contribute to the FOTON Institute’s research areas “Microwave, THz Photonics and Optical Communications” and “Photonic Sensors.”The following research topics are addressed in particular:
- Laser Sources and Laser Architectures: quantum-dot and quantum-wire semiconductor lasers; blue-emitting semiconductor lasers; VCSELs; mode-locked lasers; medium-power visible fiber lasers; single-frequency laser-based sensors for security applications; Brillouin lasers based on highly nonlinear specialty optical fibers; specialty fibers (active or hollow-core) with large effective mode areas for high-power laser applications.
- Laser Characterization: intensity and frequency noise, laser linewidth.
- Modeling: analytical methods, including mode coupling, distributed feedback, photonic mountaineering, “couplonics”, conventional (2×2) and extended (3×3) transfer matrices, generalized transfer functions, etc.; numerical methods, including nonlinear FDTD.
- Microresonators: active doped resonators and nonlinear resonators, optical micro- and nano-interferometric devices, cavity-based slow-light phenomena.
