基于原子相干效应，研究了在驻波场作用下原子介质的吸收和折射率的周期性调制所产生的周期性微结构特性及其操控。实验结果表明，在驻波场作用下原子介质存在与光子晶体同样的光子带隙特性，而且可通过调节形成驻波的两束光的频率差实现对其光子带隙位置的操控，实现了光子带隙20MHz的频率移动。

Based on the atomic coherent effects,we investigated the periodic property and its manipulation of atomic medium induced by the periodic modulation of atomic absorption and refractive index under a standing wave field.We find that there exists a photonic bandgap in atomic medium,and the position of photonic bandgap can be manipulated over a detuning range of 20 MHz via varying the frequency difference of two component fields of standing wave.
