Abstract

Time-resolved Kerr rotation spectroscopy is used to monitor the room temperature electron spin dynamics of optical telecommunication wavelength AlInGaAs multiple quantum wells lattice matched to InP. The authors found that electron spin coherence times and effective g factors vary as a function of aluminum concentration. The measured electron spin coherence times of these multiple quantum wells, with wavelengths ranging from 1.26 to 1.53 μm, reach approximately 100 ps at room temperature, and the measured electron effective g factors are in the range from -2.3 to -1.1.
