  1.

  2. Abstract : we have studied the spontaneous emission from a three - level atom with an external - driving field in a photonic crystal. as a result of quantum interference and photon localization, the population in the two upper levels displays quasi - oscillatory oroscillatory behavior. this depends on the initial atomic state and the relative positions of the two upper levels from the forbidden gap. the intensity and the phase of the external field can affect spontaneous emission from the atom. the properties are different from a three - level atom either in vacuum or in aphotonic crystal without an external driving field

    文摘:討論了在雙光子驅動場作用下，三能級原子在光子晶體中的自發發射問題.由於量子干涉和光的局域化作用，兩個上能級中的占據數將具有周期振蕩或準周期振蕩的性質，這不僅依賴于兩個上能級與禁帶的相對位置，同時也依賴于原子的初始狀態，而且還與驅動場的強度、驅動場的入射位相有關.這些性質既與真空中帶有驅動場的原子的自發發射性質不同，也有別于無驅動場作用下光子晶體中三能級原子的自發發射性質
  3. 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。
