We propose and explore a stabilization mechanism of a semiconductor laser array based on asymmetric coupling between neighboring lasers. The stabilization scheme takes advantage of the symmetry breaking of non-Hermitian potentials. We perform a comprehensive numerical analysis in terms of the design parameters, namely the distance between lasers and spatial shift between the individual laser stripe and corresponding electrode. In turn, a mirror symmetric architecture is intended to lead to a light redistribution within the array which is expected to facilitate direct coupling efficiency to optical fibers.
