The invention discloses a method for designing a focus-length-controllable and one-dimensional photonic crystal flat concave mirror. The one-dimensional photonic crystal flat concave mirror is composed of one-dimensional photonic crystals formed through the alternate arrangement of a material A and a material B. Circular rings of fixed thickness are stacked up to form the one-dimensional photonic crystal flat concave mirror, wherein the structural parameters of photonic crystals are adopted as one unit of the circular rings and the internal diameters of the circular rings are gradually increased from bottom to top. The emitting surface of the one-dimensional photonic crystal flat concave mirror is in the form of a recessed surface formed through connecting the upper edges of adjacent circular rings. According to the technical scheme of the invention, the flat concave mirror is controllable in focus length. In this way, the structural parameters of a flat concave mirror of any focal length within a certain range can be automatically designed, and the incident ray and the emergent ray are positioned at the two ends of the incident plane of the flat concave mirror. Meanwhile, the method has no special requirement on the polarization state of the incident ray, and breaks through the dependency on the polarization of surface plasmon lens. Moreover, the light focusing in both the TE polarization state and the TM polarization state is realized at the same time. The method is also applicable to linearly polarized lights. The invention has the advantages of simple design method and simple manufacture. By adopting the design method, the design cycle is shortened.
