Closely packed vertical-cavity-surface emitting laser arrays support collective modes via nearest-neighbor interactions. Nonlinear cavity-lattice dynamic equations are introduced through the derivation of intercavity coupling coefficients based on microscopic transition probabilities and the tight-binding approximation for lattice eigenstates. Ultrafast numerical simulations show array relaxation to phase-locked steady-state configurations, of fixed phase difference among nearest neighbors. Linear stability analysis derives the dispersion relation of the collective modes excited over the cavity lattice, their stability regimes, and transitions to limit cycles and chaotic behavior at high coupling strengths. Spontaneous phase selection is also analyzed.
