The influence of inner ring radius and in-plane electric field on the relative refractive index of a GaAs-AlGaAs single circular quantum ring is theoretically studied. The energy levels and corresponding wave functions are obtained by solving the Schrödinger equation within effective mass and envelope wave function approximations. The changes in the intraband transition energies are presented in terms of varying ring radius and external electric fields. Relative refractive index changes are calculated through the compact-density matrix approach. The results show that both ring radius and electric field significantly affect the location and also the peak intensities of relative refractive index changes on the incident photon energy.
