  Arrays of coupled semiconductor lasers are systems possessing radically
complex dynamics that makes them useful for numerous applications in beam
forming and beam shaping. In this work, we investigate the spatial
controllability of oscillation amplitudes in an array of coupled photonic
dimers, each consisting of two semiconductor lasers driven by differential
pumping rates. We consider parameter values for which each dimer's stable
phase-locked state has become unstable through a Hopf bifurcation and we show
that, by assigning appropriate pumping rate values to each dimer,
large-amplitude oscillations coexist with negligibly small amplitude
oscillations. The spatial profile? of the amplitude of oscillations across the
array can be dynamically controlled by appropriate pumping rate values in each
dimer. This feature is shown to be quite robust, even for random detuning
between the lasers, and suggests a mechanism for dynamically reconfigurable
production of a large diversity of spatial profiles of laser amplitude
oscillations.
