Abstract: Devices and systems which include on-chip waveguides with flattened dispersion are described. In one aspect, silicon nitride slot waveguides that exhibit four zero-dispersion wavelengths with a flattened dispersion over a wavelength range of 500 nm are obtained. The disclosed silicon nitride slot waveguides are used to generate a two-octave supercontinuum from 630 nm to 2650 nm, enabling (a) on-chip generation of 5 fs optical pulses as short as 1.3 cycles, and (b) sensitive single-shot measurements of the absolute carrier-envelope phase using a single integrated waveguide. In another aspect, silicon slot waveguides that exhibits four zero-dispersion wavelengths with a flattened dispersion over a wavelength range of 670-nm are obtained. An octave-spanning supercontinuum is generated in the disclosed silicon slot waveguide, over a wavelength range from 1217 nm to 2451 nm, approximately from bandgap wavelength to half-bandgap wavelength.
