                      dense one-dimensional microfluidic droplet arrays are
                      investigated by experiments and computer simulations. We
                      demonstrate that distinct modes can be excited by creating
                      specific ‘defect’ patterns in flowing droplet trains.
                      Excited longitudinal modes exhibit a short-lived cascade of
                      pairs of laterally displacing droplets. Transversely excited
                      modes obey the dispersion relation of microfluidic phonons
                      and induce a coupling between longitudinal and transverse
                      modes, whose origin is the hydrodynamic interaction of the
                      droplets with the confining walls. Moreover, we investigate
                      the long-time behaviour of the oscillations and discuss
                      possible mechanisms for the onset of instabilities. Our
                      findings demonstrate that the collective dynamics of
                      microfluidic droplet ensembles can be studied particularly
                      well in dense and confined systems. Experimentally, the
                      ability to control microfluidic droplets may allow the
                      modulation of the refractive index of optofluidic crystals,
                      which is a promising approach for the production of
                      dynamically programmable metamaterials.},
