Measurement and calculation of spontaneous recombination current and optical gain in GaAs-AlGaAs quantum-well structures
TL;DR: In this paper, the peak optical gain as a function of spontaneous recombination current density for GaAs quantum wells of width 25 and 58 A bounded by AlGaAs barriers was determined from measurements of spontaneous emission spectra, observed through narrow windows in the 50μm wide contact stripes of oxide isolated lasers, using only a single reference value of the optical absorption coefficient above the band edge to calibrate the measurements in absolute units.
