Abstract
Various embodiments of arrangements for optically coupling an optical waveguide to an optical unit of an optical module are provided. One embodiment is an optical module for optically coupling an optical waveguide to an optical unit. One such optical module comprises: a reference structure having a reference geometry that defines a first axis of symmetry; an optical unit having an optical axis along which light is transmitted or received, the optical unit positioned relative to the reference structure with an offset between the first axis of symmetry and the optical axis; and a coupling element that couples the optical unit to an optical waveguide, the coupling element having an eccentric hole which functions as a fiber guide and a structural geometry adapted to compensate for the offset between the first axis of symmetry and the optical axis.
