We have demonstrated that the defective photonic crystal attains exceptional optical properties by doping its defect layer with lambda type three-level atoms. We have incorporated transfer matrix formalism and observed that the crystal behaves as non-PT symmetric one by violating symmetry relations of the corresponding matrix. As a result, we have shown that the two frequency modes lying in the band gap show maximum asymmetry in reflection and absorption at critical coupling, when atom is in resonance with the defect mode which can be coherently controlled while the critical coupling remains robust when crystal is operated at off-resonance.
