Abstract
Parameter deviations, random or systematic, produce incoherently phased-locked arrays with unevenly distributed phase difference and intensity. A tolerance threshold allowing incoherent, stationary collective eigenmodes is derived. Far-field light diffusion from variable phasing is evaluated.
