Abstract: An optical phase-shift technique is demonstrated to measure the carrier lifetime of an InGaAs/GaAsSb type-II superlattice as a function of excess carrier density, showing good agreement with time-resolved photoluminescence data at low excitation. At 77 K, the minority-carrier lifetime is 369 ns. [ABSTRACT FROM AUTHOR]
