Parametric optimization on optical properties of long-wavelength GaInNAs quantum well lasers

Optical properties of strained GaInNAs/GaAs quantum well (QW) is investigated using the many-body effects theory. The theoretical transition energies and GaNAs bowing parameter are fitted into photoluminescence (PL) spectrum from experiment. The theoretical results of PL spectrum and light-current-voltage characteristic shows a very good agreement with the experimental results.
