| Abstract: | Recombination constants, carrier lifetime, linewidth enhancement factor and related parameters are examined experimentally and theoretically for MQW semiconductor optical amplifiers. The theoretical model which takes carrier overflow into account predicts a band-to-band recombination constant of B=10/sup -10/ m/sup 6//s and an Auger recombination constant of C=15*10/sup -29/ m/sup 6//s which is higher than previously reported for MQW devices. Furthermore, linewidth enhancement factors up to 30 are measured.<> |
