Abstract: In this work, we proposed a simple model for control of optical properties via an external magnetic field in a vee-type degenerated atomic medium. By numerically solving the density matrix equations in the steady-state, we show that the absorption and dispersion properties are influenced by the strength of coupling laser and external magnetic fields. Furthermore, it is found that in the presence of an external magnetic field, a medium can be switched from transparent to absorption, which corresponds with subluminal and superluminal lights. The suggestions scheme may be useful in the applications of magneto-optic switches and magneto-optic storage devices in Processing telecommunication signals.
