结果表明，在具有完全光子带隙的量子阱中，量子电动力学预言了光子与类氢原子的束缚态的发生。当原子跃迁频率位于光子带边附近时，激发态原子能级发生反常的兰姆位移，分裂成双峰。这个双重态的一个成员表现出共振荧光，而另一个能级则由近共振光子的发射和再吸收来修饰，这些光子的振幅从原子附近以指数方式衰减。
It is shown that in dielectrics exhibiting a complete photonic band gap, quantum electrodynamics predicts the occurrence of bound states of photons to hydrogenic atoms. When the atomic transition frequency lies near a photonic band edge, the excited atomic level experiences an anomalous Lamb shift and splits into a doublet. One member of this doublet exhibits resonance fluorescence whereas the other level is dressed by the emission and reabsorption of near-resonant photons whose amplitude decays exponentially from the vicinity of the atom.
