Effects of inhomogeneous line broadening on electromagnetically induced transparency (EIT) and slow group velocity Conference Paper uri icon


  • We show for the first time an explicit expression of the linewidth of an EIT resonance in an inhomogeneously broadened three-level A system, and the conditions for the dependence of the linewidth on a driving field strength. Both gaseous systems with the Doppler effect and solid media in which inhomogeneity of the crystalline fields results in a broad distribution of atomic center frequencies are considered. We find two extreme cases: in one extreme the linewidth of EIT resonance is proportional to the intensity of a drive laser. And in the other it is proportional to the Rabi frequency of a drive laser, which recovers the result obtained by Feld and Javan. The dispersive properties of EIT, leading to slow group velocity of light, in an inhomogeneously broadened system are also considered.
