The invention relates to a method for laser-based splicing of a glass fiber () onto an optical component (), comprising the following steps: 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 () on the surface of the optical component be between 15° and 45°.

Laser-based splicing of glass fibers onto optical components

The invention relates to a method for producing an optical waveguide (), the surface of which is at least partly coated with a coating material. The coating material contained in a target () is removed using laser radiation () of a processing laser or converted into another aggregate state. The coating material is then deposited on the surface of the waveguide () 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 () reflected from the target () or transmitted through the target heats-up the waveguide (), said laser radiation () being polarized and impinging the target () at a specified angle (&#x3b1;) between 10&#xb0; and 80&#xb0; relative to the surface normal.
