The threshold current density J_<th> was studied theoretically for quantum-well wire array lasers, i.e., multi-quantum-well wire (MQWW) lasers in which the carriers are confined one-dimensionally and the wave functions in each wire are coupled together. The quantum energy levels of carriers for a two-dimensional potential distribution were calculated numerically. It was found that the J_<th> value for GaAs/GaAlAs MQWW lasers is about one-half that of conventional multi-quantum-well lasers and that the characteristic temperature T_0 of J_<th> for the former is much larger than that for the latter.
