Angled fiber-based neural implant for neuromodulation

An angled fiber-based neural implant for neuromodulation and a method to manufacture such a neural implant is presented. The angled fiber-based neural implant comprises a fiber shank for inserting in neural tissue. The fiber shank comprises an optical waveguide, and the optical waveguide comprises a core and a cladding adapted so that light is able to propagate along the length of the optical waveguide. The shape of the core is arranged for providing a substantially uniform intensity distribution of light radiation from the core at the fiber tip, and the fiber tip comprises an angled surface. The end of the core and the end of the plurality of conduits are exposed at the angled surface, so that the plurality of conduits emanates at two, or more, different levels, where each level comprises a different depth into the tissue.
