摘要
Carrier lifetime has been measured in GaInAs-AlInAs multi-quantum-well structures and in thick GaInAs samples for local carrier densities between 2 multiplied by 10**1 **7 and 5 multiplied by 10**1 **9 cm-**3 . Carrier lifetime and Auger recombination are found to be very close ( plus or minus 20%) in the two structures. The Auger-limited T//0 values calculated for double-heterostructure and multi-quantum-well lasers are found to be, respectively, 93 and 170 K. Optimization of the quantum well laser as a function of the number of wells in the active region is discussed.
