摘要

GaAs/AlAs superlattices (SLs) were grown by MOCVD. The temperature dependence of photoluminescence was measured. The type II-transition dominated PL spectrum was achieved by controlling the layers thickness of GaAs and AlAs at low temperature. Such SLs with long carrier lifetime is very attractive for low crosstalk semiconductor optical amplifier applications.
