Abstract :
A simple technique for measuring absorption and gain spectra under reverse and forward bias in a two section semiconductor laser is described. Results are presented for an AlGaAs/GaAs multiquantum well laser. For reverse bias, exciton broadening and shifting are observed; and for forward bias, relative gain spectra are measured
