我们研究了具有两个跃迁的四能级原子的自发发射，该原子与在能带边缘附近具有光子带隙的库耦合。此外，从上层到辅助层的转变是由激光驱动的。考虑到外部驱动场的不同失谐，我们讨论了一些效应，例如激光诱导的暗线、激光诱导的线分裂和激光诱导的将修饰态推出带隙，这些效应源于量子干涉效应和外部驱动场的控制。
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.
