A process for the production of a glass-plastic connection which is form-fitting, and to a form-fitting composite between glass and plastic which is obtainable by the process. The process and the glass-plastic composite are characterized in that a glass, which in particular is planar, neither during the process nor in the glass-plastic composite is subjected to a mechanical load which could lead to cracks, e.g. microcracks. Accordingly, in the composite, the glass is connected to a plastic in a stress-free manner The composite of glass with plastic is especially gas-proof and/or liquid-proof.

Method for producing a glass-plastic connection

An apparatus for joining, in particular laser welding, two components, in particular plastics components, comprises&#x2014;two workpiece receptacles () for respectively holding the two components () to be connected, &#x2014;in each case one bearing element, preferably a bearing plate (), for each of the workpiece receptacles (), &#x2014;a clamping drive (SA) for at least one bearing element for feeding and bracing of the two components () held in the workpiece receptacles () during the joining process, &#x2014;a controller () for the clamping drive (SA) and in particular a laser welding device (LS), and&#x2014;a mechanically loose coupling between the clamping drive (SA) and bearing element () such that the two workpiece receptacles () are tiltable towards one another during feeding and bracing. Also disclosed is a method for operating such a joining apparatus during a joining process of two components () held in the workpiece receptacles (), in particular during a laser welding process.

An optical component, in particular a passive component, for optical waveguiding, includes: optical waveguides formed in a carrier substrate as a waveguide pattern. The optical waveguides are formed in the carrier substrate by recesses by cutting out the optical waveguide. In an embodiment, the optical waveguide is connected to the carrier substrate by web-shaped supporting structures.
