The gain characteristics in quantum-wire-laser devices in the presence of many-body Coulomb interactions are systematically investigated by using the screened Hartree–Fock theory. We quantitatively analyze the peak gain, the transparency density, and the differential gain based on numerical calculations of the optical gain spectra in a model quantum-wire laser. We found that the transparency density is almost unaffected by the Coulomb interactions, and that the Coulomb enhancement of peak gain or differential gain takes place near the transparency density. At high density, however, a significant suppression of peak gain occurs, which is a peculiar feature in quantum-wire lasers.
