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…

Toward integrated tantalum pentoxide optical parametric oscillators
Maximilian Timmerkamp, Niklas M. Lüpken, Shqiprim Adrian Abazi +3
We present a hybrid waveguide-fiber optical parametric oscillator (OPO) exploiting degenerate four-wave mixing in tantalum pentoxide. The OPO, pumped with ultrashort pulses at 1.55…
