研究了L型原子与双带光子晶体近共振相互作用时的自发辐射、吸收和色散特性。假设带边附近的各向同性色散关系，我们表明，可以发生两种不同的相干现象。首先，相邻自由空间跃迁的自发辐射谱在谱中获得"暗线"~零。第二，原子可以变得透明的探测激光场耦合到相邻的自由空间跃迁。
We study the spontaneous emission, absorption, and dispersion properties of a L-type atom where one transition interacts near resonantly with a double-band photonic crystal. Assuming an isotropic dispersion relation near the band edges, we show that two distinct coherent phenomena can occur. First the spontaneous emission spectrum of the adjacent free-space transition obtains ‘‘dark lines’’ ~zeros in the spectrum!. Second, the atom can become transparent to a probe laser field coupling to the adjacent free-space transition.
