Enhanced self-action effects and slow-light optical solitons by electromagnetically induced transparency in the two-level atom

摘要

Electromagnetically induced transparency (EIT) has been studied primarily within the context of a multilevel atomic system. We show that EIT can occur in a two-level atomic system and can lead to strong self-action effects that are not hampered by material absorption, with important implications for processes such as squeezed-light generation and the propagation of optical solitons.
