Degenerate optical parametric oscillation (DOPO) is a versatile platform for generating binary phase-states of light, with demonstrated applications in on-chip random number generation (RNG) [1] and coherent Ising Machines (IM) [2]. Kerr-based DOPOs rely on a dual-pumped spontaneous four-wave mixing process with degenerate signal and idler fields. However, DOPO is susceptible to instabilities that limit its applicability [3], and identifying stable operation parameters remains challenging. Here, we experimentally investigate the dynamics and stability of dual-pumped DOPO in a silicon nitride microring resonator in the anomalous dispersion regime.
