We consider 1d and 2d arrays of coupled optomechanical oscillators. Each of those consists of a laser-driven optical mode coupled to a mechanical mode, and it can be driven into a state of self-sustained mechanical oscillations. We analyze the dynamics of the phase field characterizing those oscillations. In the absence of noise, we find that there can be either vortex structures or spatiotemporal chaos in the phase field, depending on the system parameters. In the presence of noise (e.g. thermal or quantum fluctuations), the phase-phase correlator decays as a function of distance. We analyze this behaviour using both numerical simulations and simplified models.
