New approaches to control the flow of light are discussed, which can be operated at high frequencies where conventional optical elements are lacking. We show that high-order nonlinear light-matter interactions can selectively be induced in an electromagnetically induced transparency medium to effectively create a higher-order photonic bad gap structure. This way, the momentum of high-frequency light can be reversed via the atomic coherence created by a control field with substantially lower frequency, effectively forming a mirror. Both the backward retrieval of single photons and of continuous waves are analyzed. A proof-of-principle experiment with thermal 85Rb vapor is proposed, and potential implementations at hard x-ray energies are discussed.
