Abstract
Electromagnetically induced transparency (EIT) in an absorbing medium refers to the suppression of linear absorption of a probe laser at the line center by destructive quantum interference. The quantum interference may be destroyed by adding a switching laser coupled to a separate state in a four-state system. The four-state system exhibits unusually large nonlinear probe absorption at the EIT center and may be used to realize absorptive photon switching as proposed by Harris and Yamamoto [1].
