Blue-shifted dispersive waves and broadband UV emission using dual-core SiN waveguides
L. Xia, P. J. M. van der Slot, M. Timmerkamp +2
We show that using strongly coupled dual-core waveguides for supercontinuum generation shifts the wavelength of the high-frequency dispersive waves towards shorter wavelengths, as…

Physical mode analysis of multimode cascaded nonlinear processes in strongly-coupled waveguides
Lisi Xia, Peter J. M. van der Slot, Chris Toebes +1
We experimentally investigate on-chip control and analysis of spatially multimode nonlinear interactions in silicon nitride waveguide circuits. Using widely different dispersion of…

Chip-integrated extended-cavity mode-locked laser in the visible
Lisa V. Winkler, Govert Neijts, Hubertus J. M. Bastiaens +9
Mode-locked lasers are of interest for applications such as biological imaging, non-linear frequency conversion, and single-photon generation. In the infrared, chip-integrated mode…
