We show mathematically that the lowest-order supermode of a real-refractive-index phase-locked semiconductor diode laser array, which radiates into a single narrow far-field lobe, is favoured by its lower threshold when the gain in the interspaces between the waveguides exceeds that of the waveguides themselves.
