Abstract
The shape of the spontaneous-emission spectra of quantum-well InGaAs structures is analyzed in a wide current interval at temperatures 4.2–286 K. Using a modified homogeneous lineshape function, an interpretation of the band shape for transitions between the lowest subbands is given and the nature of its non-Lorentzian contour is discussed. The properties of a family of functions exhibiting a continuous transition from a Lorentzian to a Gaussian lineshape are discussed. They could be suitable for modeling spectra in the case of non-Markovian collisional relaxation.
