Abstract :
We describe an energy-resolved and spatially selective time domain technique for optically excited measurements of diode laser modulation responses. We report application of the technique to a study of an InGaAs-GaAs quantum well laser. We emphasize the significance of the spatial characteristics of the excitation in resolving effects related either solely to the active region or to the entirety of the laser structure.<>
