  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:讨论了在双光子驱动场作用下,三能级原子在光子晶体中的自发发射问题.由于量子干涉和光的局域化作用,两个上能级中的占据数将具有周期振荡或准周期振荡的性质,这不仅依赖于两个上能级与禁带的相对位置,同时也依赖于原子的初始状态,而且还与驱动场的强度、驱动场的入射位相有关.这些性质既与真空中带有驱动场的原子的自发发射性质不同,也有别于无驱动场作用下光子晶体中三能级原子的自发发射性质
