The optical coupling between dual elements of photonic crystal vertical cavity surface emitting laser arrays is characterized. The optically coupled microcavity lasers have independent bias injection currents. Output power and beam analysis measurements are used to quantify the effects of optical coherence in nominally 850 nm emitting arrays. Modelling and experiment show how the optical coupling is influenced by photonic crystal lattice period and the independent current injection into the elements.
