Abstract

The lifetime of the second-order population of a fully inverted inhomogeneously broadened ensemble of quantum dots (QDs) is investigated. It is assumed that a planar structure of two-level QDs is initially non-resonantly excited by a pump laser pulse. After a delay time τ, the QDs are resonantly probed by laser pulse. Calculations using the master equation approach show that the lifetime of the second-order population is proportional to the QD density which is resonant with the probe laser spectrum.
