Optical parametric oscillators (OPOs) are ubiquitous sources for efficient frequency conversion and have evolved into robust fiber technology . However, integrated waveguides offer in contrast to photonic crystal fibers a higher nonlinearity resulting in lower necessary pump energies and shorter interaction lengths . Therefore, OPOs would require smaller footprints on a chip with additionally improved stability . Here, we present a waveguide-based OPO (WOPO) exploiting four-wave mixing (FWM) in silicon nitride (Si 3 N 4 ) waveguides, with the potential to be fully integrated.
