Abstract

An excited atom in a photonic band-gap crystal can emit a photon that is then reabsorbed and reemitted by the atom, to form a dressed atom-field state. We discuss the existence conditions for such a trapped photon dressed state with a general multilevel atom driven by coherent fields and show that more than one such trapped state can exist. The field characteristics of the trapped field and the population trapped in the excited state are studied for various atomic systems. It is found that the driving field can determine the spread and energy of the trapped field, as well as the number of possible trapped dressed states.
