摘要
介绍了三维赝带隙光子晶体中原子集合的自发辐射衰减分布特性 .发现不同的原子集合弥散组态 ,其原子自发辐射呈现十分宽或窄的有限的寿命分布 .纯粹光子晶体效应可导致加速和抑制衰减过程并存 .
The characteristics of the decay distribution of spontaneous emission from an assembly of atoms in photonic crystals with pseudogaps are described.Calculations show that quite wide or narrow lifetime distributions can occur for different spreading configurations of the atoms.The pure photonic crystal effects may lead to coexistence of both accelerated and inhibited decay processes.Our results clarify theoretically the substantial discrepancies in recent reported experiments.
