Performance tradeoffs in low-loss Si3N4 waveguides for linear and nonlinear applications

• We experimentally analyze tradeoffs in terms of waveguide losses, dispersion engineering and single-mode behaviour for different waveguide geometries. Our results suggests that photonic integrated circuits relying on nonlinear waveguides benefit from including a dedicated waveguide geometry via multi-layer integration to yield a seven-fold improvement in terms of loss.
