The DOPO network with amplitude heterogeneity. a The modulated threshold gain α c of several modes and the success probability P s vs. the normalized pump rate p when ω ij = −0.1 for the worst-case instance with N = 8 vertices. b The inhomogeneous oscillation amplitudes for the first excited state at a pump rate p = 0.8. The size and color of the circle represent the amplitude and phase of each DOPO14
