  abstract = 	{Optical microdisk cavities with certain asymmetric shapes are known to possess unidirectional far-field emission properties. Here, we investigate arrays of these dielectric microresonators with respect to their emission
properties resulting from the coherent behavior of the coupled constituents. This approach is inspired by electronic mesoscopic physics where the additional interference effects are known to enhance the properties of
the individual system. As an example, we study the linear arrangement of nominally identical Lima{\c{c}}on-shaped cavities and find mostly an increase of the portion of directional emitted light while its angular spread is largely
diminished from 20 deg for the single cavity to about 3 deg for a linear array of 10 Lima{\c{c}}on resonators, in fair agreement with a simple array model. Moreover, by varying the intercavity distance, we observe windows of
reversion of the emission directionality and superdirectionality that can be interesting for applications like optical sensing or interconnects. We introduce a generalized array factor model that takes the coupling into account.},
