We analyze the optical response of a standing-wave driven four-level atomic system with double dark resonances. Fully developed double photonic band gaps arise as a result of periodically modulated refractive index within the two electromagnetically induced transparency widows. We anticipate that the dynamically induced band gaps can be used to coherently control the propagation of light-pulses with different center frequencies and may have applications in all-optical switching and routing for quantum information networks.
我们分析了具有双暗共振的驻波驱动四能级原子系统的光学响应。由于在两个电磁诱导透明窗口内折射率的周期性调制，出现了完全发展的双光子带隙。我们预计，动态诱导的带隙可用于相干控制具有不同中心频率的光脉冲的传播，并可能在量子信息网络的全光开关和路由中得到应用。
