Abstract:
1. A method for making optical connections with optical waveguides, comprising: mounting the optical waveguides or a device comprising the optical waveguides, on a component carrier; embedding at least a partial region of the optical waveguides in a volume of resist material; detecting positions of the optical waveguides to be connected with reference to a coordinate system using a measuring system; determining a favorable, three-dimensional geometry for at least one connecting optical waveguide structure for connecting the optical waveguides to each other at predetermined connecting locations and converting the at least one connecting optical waveguide structure geometry to a machine-readable dataset; three-dimensional structuring of the at least one connecting optical waveguide structure geometry in the volume of the resist material using a direct-writing lithography device operating on the basis of the machine-readable dataset; treating the structured resist material using at least one of physical methods and chemical methods to form the at least one connecting optical waveguide structure having ends connected to respective predetermined connecting locations of the optical waveguides; and developing the structured resist material to remove non-exposed regions of the resist material to generate at least one freestanding connecting optical waveguide structure having a refractive index contrast between a core region and a cladding region of at least 0.01.
