Supercontinuum generation in media with sign-alternated dispersion
Haider Zia, Niklas M. Lüpken, Tim Hellwig +2
When an ultrafast optical pulse with high intensity is propagating through transparent material a supercontinuum can be coherently generated by self-phase modulation, which is esse…

Ultrafast, low-power, all-optical switching via birefringent phase-matched transverse mode conversion in integrated waveguides
Tim Hellwig, Jörn P. Epping, Martin Schnack +2
We demonstrate the potential of birefringence-based, all-optical, ultrafast conversion between the transverse modes in integrated optical waveguides by modelling the conversion pro…
