Ultrafast QPM for the generation higher-order DW using resonance-enhanced microstructured fibers
On demand | Presented live 14 April 2026 
Abstract
We explore ultrafast quasi-phase-matching (QPM) in resonance-enhanced microstructured fibers for generating higher-order dispersive waves. By modulating waveguide dispersion through nanofilm coatings, we investigate sideband formation using numerical simulations and proof-of-concept experiments. The study combines modeling and experimental feedback to optimize fiber and excitation parameters, enabling tunable dispersive-wave generation. These findings contribute to the development of broadband light sources for ultrafast photonics and spectroscopy.
