Dynamic and radiative properties of a Λ-type atom embedded in a three-dimensional anisotropic photonic crystal with a driven field are investigated. The time-evolution properties of the atom and the characteristics of the emission field are greatly affected by the position of the upper level relative to the forbidden gap. Also studied are the influence of the intensity of the external field, the detuning from resonant frequency, and the background decay parameter on the dynamic properties of the atom. The energy of the propagation field is translated partly into the form of the diffusion field during the propagating process. The spectra of the propagation component and diffusive component are dependent on the distance from the atom.
