Abstract
We study the spontaneous emission of a four-level atom with two transitions coupled to a reservoir that has a photonic bandgap near the band edge. Moreover, the transition from the upper level to an auxiliary level is driven by a laser. Considering the different detuning of the external driving field, we discuss some effects, such as a laser-induced dark line, a laser-induced line splitting, and a laser-induced pushing of a dressed state out of the bandgap, which originate from the quantum interference effect and control of the external driving field.
