Nonlinear Optics
Ultra-Stable Supercontinuum [MPL]
Markus Lippl
At the Max Planck labs, we investigate nonlinear optics in microstructured fibres for the generation of low-noise supercontinuum light. To achieve this, we design all-normal dispersion (ANDi) fibres that rely exclusively on self-phase modulation (SPM) to broaden the input spectrum. SPM is a coherent and deterministic nonlinear mechanism, enabling stable, low-noise spectral output [1].
We recently demonstrated that twisting the fibre (t-ANDi) further enhances performance by robustly preserving the polarization state across the entire supercontinuum bandwidth [2,3].
These fibres have several applications, and we collaborate with groups worldwide to explore them:
- With the group of Albert Stolow (Uni. of Ottawa), we are advancing hyperspectral stimulated Raman scattering (SRS) microscopy by improving both sensitivity and polarization control. This enables polarization-resolved, modulation-enhanced hyperspectral SRS imaging [4].
- With the group of Jean-Michel Ménard (Uni. of Ottawa), we are pushing the limits of electro-optic sampling for single-shot detection of terahertz (THz) pulses [5,6].
