Job Description
Missions
The OML (Optics, Materials and Lasers) team at CIMAP is offering a postdoctoral position in the field of mid-infrared photonics and functional optical materials. The project focuses on the development of low-phonon-energy rare-earth-doped materials for compact mid-infrared light sources and optical sensing applications.
The research will encompass both crystalline and amorphous materials, including fluoride- and chloride/bromide-based compounds, with particular emphasis on emerging lead-free double perovskites. The main objectives include investigating their optical spectroscopic properties, evaluating their laser performance, and assessing their potential for photonic integration. Special attention will be devoted to the characterization of photonic microstructures, such as femtosecond-laser-written waveguides and Bragg reflectors, with the aim of integrating them into compact photonic architectures.
This interdisciplinary project is structured around three complementary research areas: (i) materials science; (ii) advanced optical spectroscopy with submicron spatial resolution; and (iii) the development of photonic components and laser demonstrations operating in the 2–6 µm spectral range.
The project is closely aligned with CIMAP's research activities in fluoride photonics, integrated optics, and rare-earth-doped laser materials. It will also benefit from collaborations with several leading international academic partners, including the University of Salamanca, the University of Adelaide, and the Freiburg Materials Research Center.
Activity
The research project will encompass both crystalline and amorphous materials, including fluoride- and chloride/bromide-based compounds, with particular emphasis on emerging lead-free double perovskites.

Special attention will be devoted to the characterization of photonic microstructures, such as femtosecond-laser-written waveguides and Bragg reflectors, with the aim of integrating them into compact photonic architectures.
The postdoctoral researcher will actively contribute to the dissemination and promotion of scientific results through publications in high-impact international journals, participation in major international conferences, and presentations at national scientific and educational events, including thematic workshops and thematic days.
Your Profil
Skills
The successful candidate must hold a PhD in Physics, Photonics, Materials Science, or a related field. Experience in one or more of the following areas will be highly valued: optical spectroscopy of rare-earth-doped materials, laser physics and photonics, femtosecond laser micromachining, and integrated optics.
A strong motivation for interdisciplinary experimental research and a good command of scientific English are essential. The candidate will work closely with PhD and Master's students within the team and will contribute to a collaborative and international research environment.
Your Work Environment
The project will be carried out within the OML (Optics, Materials and Lasers) team at CIMAP, a dynamic and international research group comprising more than 20 researchers, engineers, postdoctoral fellows, and students working in optics, photonics, laser physics, and advanced materials. The team is internationally recognized for its expertise in fluoride materials, rare-earth spectroscopy, and laser development.
The laboratory provides access to state-of-the-art experimental facilities, including: (i) advanced materials characterization tools (SEM–EDX, confocal laser microscopy, and µ-Raman spectroscopy); (ii) cutting-edge optical spectroscopy platforms for the mid-infrared spectral range, including cryogenic spectroscopy capabilities; and (iii) a dedicated platform for the development of waveguides and integrated laser devices.
The successful candidate will work in close collaboration with research engineers, PhD students, and international partners within a dynamic, interdisciplinary, and highly collaborative scientific environment.
