We theoretically and experimentally investigate the lateral mode behavior of quantum-dot lasers, and demonstrate the absence of filamentation up to 10/spl times/ threshold. The negative linewidth enhancement factor necessary for filamentation in highly-excited quantum dot lasers originates from the Coulomb coupling between quantum-dot and quantum-well states.
