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。

In order to be tuned the energy gap of a semiconductor with respect to a fixed gas laser line, the resonant Raman scattering were performed by means of the variation of the energy gap with the temperature in the sample. 利用半导体带隙随温度变化,使它与固定激光线调谐,曲此完成共振散射实验。
As it shows, the properties of spontaneous emission depend not only on the relative position of the resonant frequency from the edge of the photonic band gap and the photonic mode density but also on the intial atomic state. 结果表明,其自发辐射除了依赖于原子上能级与光子频率带隙边缘的相对位置或光子态密度外,还依赖于原子的初始状态。
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。
