英文摘要	we investigate the interband optical absorption spectra near the band edge of a cylindrical semiconductor quantum wire in the presence of a static electric field and a terahertz electric field polarized along the axis. optical absorption spectra are nonperturbatively calculated by solving the low-density semiconductor bloch equations in real space and real time. the influence of the franz-keldysh (fk) effect and dynamical fk effect on the absorption spectrum is investigated. to highlight the physics behind the fk effect and dynamical fk effect, the spatiotemporal dynamics of the polarization wave packet are also presented. under a reasonable static electric field, substantial and tunable absorption oscillations appear above the band gap. a terahertz field, however, will cause the autler-townes splitting of the main exciton peak and the emergence of multiphoton replicas. the presented results suggest that semiconductor quantum wires have potential applications in electro-optical devices.
