Photon and Carrier Density Profiles in a Semiconductor Optical Amplifier
We investigate, experimentally and theoretically, the optical amplification and its saturation in a mirrorless semicondctor quantum well laser. We optically excite a narrow stripe of variable length and measure the profiles of spontaneous and stimulated luminescence spectra. Comparison of theory and experiment reveals that saturation is mainly caused by carrier depopulation through stimulated electron-hole recombination, and by the loss of light travelling in the direction of the stripe.
