Susceptibility of a two-level atom near an isotropic photonic band edge: transparency and band edge profile reconstruction
arXiv:1503.04318 · doi:10.1016/j.physa.2015.01.044
Abstract
We discuss the necessary conditions for a two-level system in the presence of an isotropic band edge to be transparent to a probe laser field. The two-level atom is transparent whenever it is coupled to a reservoir constituted of two parts - a flat and a non-flat density of modes representing a PBG structure. A proposal on the reconstruction of the band edge profile from the experimentally measured susceptibility is also presented.
