Abstract

We theoretically demonstrate that complete absorption of light can be realized in a heterostructure composed of a thick metal film and truncated photonic crystals with a lossy dielectric defect. Because of the coupling between the interface mode and the defect mode, all of the light can enter the heterostructure. Meanwhile, the fields are enhanced remarkably in the defect, so the light is fully absorbed by the lossy defect. When the coupling between two different localized modes is strong, two absorption peaks are obtained, while a weak coupling leads to a narrow absorption band due to the degeneracy of two localized modes.
