Abstract

We model the slow-light phenomenon using electromagnetically induced transparency from spin coherence in [110] quantum wells. The long electron-spin lifetime in [110] quantum wells and the strain-induced shift of the light-hole-like excitonic transition energy below those of the heavy-hole-like continuum states can enhance the performance of slow light. The optical anisotropy due to band mixing and strain in [110] quantum wells is properly taken into consideration. By using light-hole-like excitons, the delay of a probe light with TM polarization in an optical waveguide controllable by an intense pump is made possible with the aid of long spin coherence.
