The excitonic absorption spectra of nanoring double quantum wells (NDQWs) subjected to radial and lateral electric fields are theoretically investigated. The electro-optic excitonic absorption spectra show very different behaviors for different electric-field configurations. The evolution of the main excitonic peaks of the NDQW with the radial electric fields is similar with that of square double quantum wells. Since the circular symmetry of the NDQW is not destroyed, the absorption peaks associated with ring structure are insensitive to the radial electric fields. However, because of the loss of such symmetry, these absorption peaks are broadened into continuum even at low lateral electric fields. Meanwhile, due to the exciton ionization and the inhomogeneous electric-field effect, the main excitonic peaks are intensively broadened and reduced by the lateral electric fields.
