High-Polarization-Extinction Raman Conversion in Gas-Filled Polarization-Maintaining Hollow-Core Fibers
Xianhao Qi, Pau Arcos, Yizhi Sun +4
Gas-filled hollow-core fibers (HCFs) have emerged as a versatile platform for high-power nonlinear optics, enabling phenomena from ultrafast pulse compression to broadband frequenc…

Scaling of nonlinear dynamics driven by stimulated Raman scattering in gas-filled hollow-core fibers
Pau Arcos, Arturo Mena, MarÃa Sánchez-Hernández +4
Optical systems are scalable under low-intensity illumination since their governing equations are linearly dependent of the optical signal strength. Nonetheless, in high-intensity…

Stimulated Raman Scattering and Molecular Modulation in Anti-resonant Hollow-core Fibres
Pau Arcos, Arturo Mena, MarÃa Sánchez-Hernández +5
Raman scattering is the inelastic process where photons bounce off molecules, losing energy and becoming red-shifted. This weak effect is unique to each molecular species, making i…
