We investigate the spontaneous emission of a two-level atom embedded in one-dimensional photonic crystals (PCs). The delay Green function, which captures many of the physically relevant aspects of the problem is deduced from the structure of the one-dimensional PCs. The population involution and distribution of upper level are investigated by utilizing the delay Green function. Especially, it is shown that the spontaneous emission is switched on and off by nonlinear tuning of photonic density of states of the one-dimensional PCs. And we emphasize here that the methodology can also be applied to alternate left-right handed PCs. It is shown that the photon-atom bound state is present even when the atom is embedded in alternate left-right handed material PCs.
Keywords:photonic band gap, quantum interference, spontaneous emission
