| 英文摘要 | theoretical calculations of the interband optical-absorption spectra of a finite quantum dot superlattice in a wire (qdslw) in the presence of a homogeneous dc or terahertz field are presented. the qdslw has miniband structures of the electron states as general quantum well superlattices do and shows the two features common to one-dimensional structures, viz., strong excitonic absorption below and weak absorption above the band edge. the applied dc field causes a redshift of the location and a decrease in height of the main excitonic peak and leads to an increase in height of the minor peak next to the main peak. in the presence of a terahertz field, the autler-townes splitting of the main excitonic peak and the emergence of one-photon and two-photon gain peaks on the spectra are demonstrated.
