Gain and refractive-index spectra for bulk and quantum-well semiconductor lasers are computed using quantum-mechanical many-body theory. The results clearly show the influence of band-gap renormalization, broadening, and Coulomb enhancement on the gain, the absorption, and the refractive-index spectra.

  10. The material parameters for bulk GaAs are ER = 4.2 meV, a0 = 12.4 nm, me = 0.0665m0, mh = 0.52m0, and Ħγ = 1ER (0.1ER) for T = 300 K (10 K). Eg = 1522 meV − 0.58T2/(T + 226 K) meV/K according to C. K. Kim, P. Lautenschlager, M. Cardona, Solid State Commun. 59, 797 (1986). [CrossRef]
  11. For quasi-two-dimensional GaAs we take the bulk parameters, except that Eg is increased by 120 meV. The energies are scaled to the three-dimensional Rydberg energy.
