The spontaneous emission of a three-level A-typed atom embedded in anisotropic photonic crystals with two coherent bands is investigated.The relative position of the atom is described by a position-dependent parameter θ(ro),in regard as the coherence of the two bands.The spectrum of the transition in free space vacuum is discussed.The spectral center can be manipulated by the coherent parameter θ(ro),and the spectral intensity can be adjusted via the atomic transition in the coherent photonic reservoir.
