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。 -
On the other hand, the electric field and intensity distributions of the he11 mode in the hollow fiber are calculated by using the exact solutions of maxwell equations based on the vector model, and the diffracted near - and far - field distributions of the he11 - mode output beam under the fresnel approximation are studies. we derive an analytical expression on the far - field distribution of the he n - mode output beam in free space and discuss its applicable condition. we also analyze and compare the differences between the he11 - and lp01 - mode output beams, and find that the near - field distribution of the lpoi - mode output beam is a gaussian - like one, but the near - field distribution of the he11 - mode output beam is a doughnut - like one, whereas the far - field distribution of both the lp01 - and he11 - mode output beams are a doughnut one
此外，我們把中空光纖中lp _ （ 01 ）模（標量模型）和he _ （ 11 ）模（矢量模型）的場分佈以及它們各自的輸出光束的近場與遠場分佈進行了比較，發現兩種模式的輸出光束在近場分佈有很大的區別， lp _ （ 01 ）模輸出光束在近場是一個高斯分佈，而he _ （ 11 ）模輸出光束在近場是一個中空光束，在遠場兩種模式的輸出光束分佈是基本一致的，這正是由於在中空光纖中採用了弱波導近似以後所引起的誤差。 -
