In this letter, the spontaneous emission from a three-level atom embedded in a photonic band gap structure is studied. The quantum interference between two decay processes affects the atomic splitting of the upper levels into dressed states, and leads to some novel behavior of the populations in the excited states: complete decay and no population inversion between the upper levels, which are quite different from that of two-level atoms in a photonic crystal.
