We investigate the two-dimensional (2D) optical absorption spectrum in a semiconductor quantum dot nanostructure driven by two orthogonal standing-wave lasers. It is found that, due to the position-dependent quantum interference effect, the 2D optical absorption spectrum can be easily controlled via adjusting the system parameters. Thus, our scheme may provide some technological applications in solid-state optoelectronics.
