Abstract
We investigate the absorptive–dispersive properties of a weak probe field in a ladder-type quantum dot. It is found that the enhanced refraction index without absorption can be easily controlled via adjusting properly the corresponding parameters of the system. Our scheme may provide some new possibilities for technological applications in dispersion compensation and solid-state quantum communication for quantum information processing.
