    Abstract: The invention relates to an arrangement for supplying luminous energy to biological structures, comprising a pumping light source and/or a laser source, an optical beam forming system, and an optical waveguide which is coupled to the beam forming device to create a light intensity profile dependent on the full length of the waveguide and/or a change in shape and which comprises a core and a cladding surrounding the core, a distal fiber end being free. The arrangement is characterized by a depressed refractive index structure which extends across the core and the cladding and consists of a succession of concentric zones that are designed, in at least some sections in the radial direction, as an alternating succession of regions having a relatively low refractive index and a relatively high refractive index. In a method for producing an optical waveguide for an arrangement for supplying luminous energy in a targeted manner to biological structures, a diffractive index profile that is variable in the longitudinal direction of the optical waveguide is created by providing a glass tube having a first refractive index, coating the glass tube with at least one coating having a second refractive index, drawing the coated glass tube to create a capillary, and collapsing the capillary within a specific area and along a specific length to create a collapsed section.
