About the project
Current nonlinear fiber optic devices mainly focus on the visible and near-infrared bands. The project focuses on the development of mid-infrared (MIR) nonlinear optics and integrated nonlinear devices using soft-glass optical fibers to achieve efficient light generation and manipulation in the 2–20 µm spectral region.
MIR nonlinear fiber devices are not only at the forefront of nonlinear optics research but also serve as key enabling technologies for high-sensitivity sensing, broadband light sources, and next-generation laser systems, with strong demand in precision spectroscopy, metrology and quantum optics.
The research will investigate nonlinear phenomena in chalcogenide and tellurite microstructured optical fibers (MOFs), employing numerical modeling to optimize dispersion profiles and modal properties for enhanced nonlinear interactions. Building on these theoretical studies, experiments will explore supercontinuum generation, MIR solitons, Raman scattering, and dispersive wave formation, etc.
The project will also develop compact nonlinear devices such as all-fiber wavelength converters and ultrafast pulse sources. Precision drawing combined with advanced post-processing will ensure low loss and mechanical robustness. Comprehensive characterization of nonlinear parameters, power handling, and spectral output will guide iterative improvements, culminating in a new class of low-loss MIR nonlinear fibers and device prototypes capable of broad, stable supercontinuum output and tunable wavelength generation for spectroscopy and free-space communication.
