a Large field of view image of a thick nitride chip with a broad scan of ring resonator designs and straight waveguides. The green and blue highlighted regions correspond to devices tested in (c) and (d). b Dark-field optical micrograph of the ring resonator device used for Kerr-comb measurement. c Optical spectrum of the ring resonator output showing the onset of optical parametric oscillation. d Broadband supercontinuum spectra from the different width waveguides circled in light blue in (a)
