An apparatus and method for fabricating a thin layer periodic structure by successively depositing alternating uniform layers of two or more different dielectric materials on a substrate utilizing centrifugal force in a novel spin coating technique. In an alternate embodiment of the present invention, the novel spin-coating technique is configured for fabricating chiral media by successively depositing layers of one or more anisotropic materials, while rotating the substrate by a predetermined angle between deposition of each layer. In both embodiments of the inventive apparatus, a defect layer may be introduced by depositing a defect material in a desired position in the media.
