Intensity-dependent dispersion under conditions of electromagnetically induced transparency in coherently prepared multistate atoms
MetadataShow full item record
nterest in lossless nonlinearities has focussed on the dispersive properties of ? systems under conditions of electromagnetically induced transparency (EIT). We generalize the ? system by introducing further degenerate states to realize a "chain ?" atom where multiple coupling of the probe field significantly enhances the intensity-dependent dispersion without compromising the EIT condition.
