摘要：
We demonstrate slow light in dye-doped chiral liquid crystals. The medium combines a nematic liquid crystal with methyl-red and chiral agents. When a circularly polarized pump and a pulse beam interact in the cell, the output pulse is delayed thanks to the dispersive properties of the beam coupling occurring in the medium. The origin of the slow-light effect is explained on the basis of photo-isomerization induced transparency of the dye molecules hosted in the chiral liquid crystal structure.
