Abstract: The invention relates to a method for laser-based splicing of a glass fiber (1) onto an optical component (3), comprising the following steps: arranging both surfaces to be spliced substantially parallel to each other and at a predefined distance from each other; and aiming a laser beam (4) at the optical component (3). In order to specify an improved method in which the properties of the joining partners are maintained to the greatest extent during splicing, which exhibits high reproducibility and in particular is suitable for splicing joining partners of different cross-sections, the invention proposes that the angle of incidence of the laser beam (4) on the surface of the optical component be between 15° and 45°.

Abstract: The invention relates to a method for producing an optical waveguide (1), the surface of which is at least partly coated with a coating material. The coating material contained in a target (4) is removed using laser radiation (6) of a processing laser or converted into another aggregate state. The coating material is then deposited on the surface of the waveguide (1) and forms a coating thereon, said coating modifying the light guidance. It is the object of the present invention to provide an improved method for producing optical waveguides, in which guidance of undesired electromagnetic radiation and/or guidance of radiation in undesired areas of the waveguide is avoided. To this effect, the present invention proposes that the laser radiation (7) reflected from the target (4) or transmitted through the target heats-up the waveguide (1), said laser radiation (6) being polarized and impinging the target (4) at a specified angle (?) between 10° and 80° relative to the surface normal.

Abstract: A device for joining and tapering optical components such as fibers includes a retaining device for holding optical components in a processing site, a laser radiation source for emitting a laser beam and beam forming elements for guiding the laser beam to the processing site. At least a first beam forming element is inserted into the beam path of the laser radiation source for producing a radiation having the form of an annulus and a second beam forming element is provided for specifying the angle of incidence of the radiation having the form of an annulus onto the optical components at the processing site.

Abstract: The invention relates to a method for a pattern representation of inhomogeneous crossing grids of warp and weft yarns, in which a) an inhomogeneous real crossing grid is predetermined based on the real warp yarn density and the real weft yarn density, b) a homogenous virtual point grid with considerably increased resolution is overlaid onto the inhomogeneous real crossing grid, c) a pattern is represented in the homogenous virtual point grid, and d) those points of the virtual homogenous point grid are determined which coincide with crossing points of the real inhomogeneous crossing grid of the pattern.
