Gaining control over nonlinear pulse dynamics during their evolution along a waveguide is a profound technological challenge in photonics. Here, we demonstrate local control of ultrafast nonlinear dynamics using a novel photonic platform consisting of highly nonlinear liquid-core fibers, where longitudinal…
In this work, we demonstrate the optical heating modulation of soliton-based supercontinuum generation through the employment of multi-walled carbon nanotubes (MWCNTs) acting as fast and efficient heat generators. By utilizing highly dispersion-sensitive liquid-core fibers in combination with MW-CNTs…
This work presents the results of temperature-based control of supercontinuum generation in liquid-core step-index fibers. The key parameter adapted via temperature is the group velocity dispersion of the fiber modes, which determines the nonlinear pulse dynamics. Different soliton dynamics, e.g. fission,…
Structured light has enabled access to new physics and applications, and has particular potential in nanoscience. Here, we present a concept for creating light fields with constant intensity along all three spatial directions—a light strand— within externally accessible liquid-filled nanochannels integrated…
The emission of resonant radiation from temporal solitary waves—also known as dispersive wave generation—allows efficient energy transfer to far‐distant spectral domains. This coherent radiation can deliver large spectral densities at selected wavelengths once control over the individual soliton is achieved.…
Abstract Evidence of intermodal dispersive wave generation mediated by intermodal cross‐phase modulation (iXPM) between different transverse modes during supercontinuum generation in silicon nitride waveguides is presented. The formation of a higher‐order soliton in one strong transverse mode leads to…
