Optical Thin-film Structure with a Distributed Cavity

In an optical thin-film structure (2) with a periodic variation of the refractive index along an optical axis (1), wherein the variation comprises a multiplicity of periods and wherein an optical length of the periods is increased along the optical axis (1) within the thin-film structure (2), in order to form an optical cavity between distributed Bragg reflectors, the increase in the optical length for forming the optical cavity is distributed over a plurality of periods of the variation of the refractive index.
