通过原子上能级与光子频率带隙边缘的相对位置或者光子态密度，可以抑制或增强原子的自发辐射。
Spontaneous emission can be totally suppressed or strongly enhanced depending on the relative position of the resonant frequency from the edge of the photonic band gap and the photonic mode density.
光子晶体的基本特征是具有光子带隙，频率落在带隙中的光将不能传播，这使其比普通光学材料具有更广泛的应用。
The transmittance of light is forbidden in a wavelength range called photonic band gap. Photonic crystals have broader application prospect than common optical materials.
