Abstract

Gain characteristics of GalnAsP/AlGaAs lasers with ridge-waveguide structure emitting in the 600 nm band are measured using the Hakki-Paoli method. From the gain vs. current curve, the gain constant β and the current density at transparency J₀ are estimated. The values obtained are 1.3 x 10^-2 cm-μm/A and 14.3 kA/nm²- μm, respectively. Results obtained by other researchers for the same physical quantities for GalnAsP and other materials are cited for comparison purposes.
