Abstract

We have used the 830 nm, subpicosecond output of a mode-locked Ti:sapphire laser, together with subpicosecond 3.55 mu m pulses from asynchronously pumped optical parametric oscillator, to perform room-temperature, time-resolved, differential transmission measurements on a multiple quantum well structure with AlGaSb barriers and GaInSb/InAs superlattice wells. From these measurements, we have determined a Shockley-Read-Hall rate of 2.4X10(8) s(-1) and an Auger coefficient of 7x10(-27) cm(6)/s. In addition, we estimate the carrier capture efficiency into the wells cm to be similar to 52% and have demonstrated that carrier cooling, cross-well transport, and capture are complete within similar to 10 ps after excitation.
