Such control can be realized in case where a atom interact with photonic band gap matericals when the atom is placed in photonic crystals whose density of modes is dramatically different from that of free space vacuum. it was known that control could be achieved by varying the frequency ( which leads to the changes of the relative position of the upper levels from the forbidden gap ) or by varying the photonic density of modes ( dos ) or by varying the intial atomic state
由於光子晶體具有不同於真空中的光子態密度，原子和光子帶隙材料便發生相互作用，這樣便可以控制原子的自發輻射。改變原子上能級與光子禁帶邊緣的相對位置、材料中的光子態密度或原子初態都可以控制原子的自發輻射。 -
