a Electric-field amplitude distributions of an TE00 mode at 1560 nm and of an TM20 mode at 780 nm. b Effective refractive indices of the pump mode (solid line) and of the signal/idler mode (dashed line) with different 3C-SiC film thicknesses as a function of the waveguide width. c Dispersion of the TM20 pump mode (solid line) and of the signal/idler TE00 mode (dashed line). d Calculated map of the non-degenerate difference-frequency generation (DFG) phase-matching condition.
