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.
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。
It also showed that the optical absorption edge of the annealed film appeared shifted towards the longer wavelength side and the band gap decreased by 0.
光学性质显示退火处理的薄膜吸收边缘明显的向长波的方向移动,发生红移现象,而且禁带宽度减少了0。
The duration of bound-entangled state (non-distillable) is controlled by the resonant control laser and the detuning of the atomic frequency inside the gap with respect to the band-edge.
束缚纠缠态(不能提纯的纠缠态)在系统中的持续时间由驱动场的拉比频率以及原子能级和光子晶体禁带带边的相对位置决定。
