In this letter, the first detailed theoretical study of optical gain in serpentine superlattice quantum wire arrays grown on GaAs vicinal substrates is presented. In the calculations, the complex nature of the miniband structure due to coupling between wires and the valence band intermixing are taken into account. In addition to the ideal structure, the effects of imperfect Al segregation between GaAs wires and AlGaAs barriers are also investigated.
