Abstract
The invention relates to an apparatus for generating azimuthally or radially polarized radiation by means of an optical waveguide (), wherein the optical waveguide () has a structure which is suitable for conducting azimuthally or radially polarized modes (). The invention proposes that the azimuthally or radially polarized modes () in the optical waveguide () have different effective refractive indices and, within the optical waveguide (), a narrow-band grating () is arranged, in particular a fiber Bragg grating () which is designed such that the spectral distance between two azimuthally or radially polarized resonant modes () is equal to or greater than the associated spectral bandwidth.
