(a) Permittivity functions for the quantum well layer calculated using the effective conductivity model (\({\varepsilon }_{\perp }^{ECM}\), dashed lines) and the full theory (\({\varepsilon }_{\perp }^{QW}\), solid lines). (b) Optical absorption of a single quantum well per unit area calculated using either our new microscopic theory (solid line) or the effective conductivity model (calculated using Eq. 2, dashed line). (c) Dependence of \({L}_{eff,n}\) on photon energy. Only the energy ranges indicated in red are optically active. Outside of these energy ranges, optical transitions are forbidden due to Pauli blocking effects.
