Electromagnetic Induced Transparency

Zeng Zhi-qianga

The principle of electromagnetically induced transparency in a three-level atomic system is studied by means of the semi-classical theory.Electromagnetically induced transparency is one of the quantum interference effects between the external field and the atomic system.The explanations of these phenomena are given by using the dressed states.Additionally,the subluminal light is accompanied by electromagnetically induced transparency.

We show that application of self-induced transparency (SIT) solitons as a driving field in V-type electromagnetically induced transparency (EIT) leads to ;;mixed induced transparency' (MIT) that nicely combines the best features of both SIT and EIT.

Electromagnetically induced transparency in a multilevel system is investigated in ${}^{173}$Yb. The level structure investigated is ``open'' in that the light that gives rise to the transparency also resonantly couples the atoms to excited states which do not exhibit electromagnetically induced transparency. The resulting reduction of transparency is investigated experimentally and theoretically. It is found that, while the transparency is poor in certain regimes, it can be made to perform arbitrarily well in the limit of a large intensity imbalance between the optical fields.
