We consider arrays of coupled optomechanical cells, each of which consists of a laser-driven optical mode interacting with a mechanical (vibrational) mode. The mechanical modes can settle into stable finite-amplitude oscillations. We study the collective classical nonlinear dynamics of the phases of these oscillators, which is described by a certain extension of the well-known Kuramoto model. When including noise in our model, we find connections to the physics of surface growth. Besides, in two-dimensional arrays, we find that spiral structures and their dynamics play an important role.
