Abstract (en)

[origin: WO2006032654A2] The invention relates to a method for creating a structure (22) within the surface of an optical waveguide (11) by means of a laser (13), laser ablation being used in said method. The advantage of laser ablation-aided production lies in the fact that the structure (22), which is composed of parallel channels (25), for example, can be produced with great accuracy while the cross section of the optical waveguide (11) is weakened to a relatively small extent as a result of the constant depth of the channels produced by means of laser ablation. In addition, the damping rate of the optical waveguide, which is created by the structure (22), can advantageously be determined in an optical manner during production, thus advantageously making it easy to assure quality. Also disclosed is an optical waveguide whose structure comprises a regular pattern of individual structured elements such as channels (25) which are configured at a constant depth inside the surface.
