Topic description

Context : This PhD project is part of the ANR FIRST-LIGHT program, which aims to develop compact, ultra-broadband light sources and sensors covering both the mid- and far-infrared regions, using advanced glass and optical fiber technologies combined with state-of-the-art laser systems. The project seeks to bridge the gap between recent advances in mid-infrared photonics and the terahertz domain, recognizing the far-infrared (12–50 µm) as a major remaining frontier in the electromagnetic spectrum. This multidisciplinary effort lies at the interface of materials chemistry, nonlinear optics, and spectroscopy. It focuses on advancing the state of the art by developing novel nonlinear optical glasses, controlling broadband frequency conversion processes driven by ultrashort laser pulses, and enabling fiber-based platforms for far-infrared spectroscopy.

Methodology and tasks : The PhD candidate will be responsible for the synthes...
