Energy‐lose induced unidirectional light propagation were found in porous alumina based photonic crystal heterostructures. The reflected colors of the sample on the front and back sides illuminations are quite different, however, the transmitted colors have no obvious difference. This kind of unidirectional light propagation can be modulated over the whole visible light region by adjusting the combination of different photonic bandgap as well as the view angle.
