  We propose and explore a physical mechanism for the stabilization of the
complex spatiotemporal dynamics in arrays (bars) of broad area laser diodes
taking advantage of the symmetry breaking in non-Hermitian potentials. We show
that such stabilization can be achieved by specific pump and index profiles
leading to a PT-symmetric coupling between nearest neighboring lasers within
the semiconductor bar. A numerical analysis is performed using a complete
(2+1)-dimensional space-temporal model, including transverse and longitudinal
spatial degrees of freedom and temporal evolution of the electric field and
carriers. We show regimes of temporal stabilization and light emission spatial
redistribution and enhancement. We also consider a simplified (1+1)-dimensional
model for an array of lasers holding the proposed non-Hermitian coupling with a
global axisymmetric geometry. We numerically demonstrate a two-fold benefit:
the control over the temporal dynamics over the EELs bar and the field
concentration on the central lasers leading to a brighter output beam,
facilitating a direct coupling to an optical fiber.
