Optomechanical systems, that couple light to nanomechanical motion, have seen rapid progress during the past few years and have now entered the quantum regime of motion. In addition, it is now becoming possible to build optomechanical arrays, i.e. arrays of many interacting localized optical and mechanical modes. This opens up several new areas for optomechanical systems, such as quantum information processing with many mechanical modes, collective dynamics, and quantum simulations. In this talk I will focus on the nonlinear collective dynamics in such arrays. In the classical regime, mechanical oscillations can synchronize. The evolution of the mechanical oscillation phase field can display interesting phenomena, such as vortices. The transition from the incoherent regime to a synchronized regime can be determined either by static disorder or by noise. In particular, I will describe what happens under the influence of quantum noise.
