Abstract
Abstract A method of coupling an optical fiber to an optoelectronic component including a substrate having an optical waveguide therein, the waveguide opening into a notch formed in or on a first face of the substrate, including the steps of pre-positioning the optical fiber in a groove of an optical fiber support, the groove terminating at a first face of the optical fiber support, positioning the fiber support such that the first face of the substrate and the first face of the fiber support are directly opposite each other, the first faces forming a gap therebetween, and positioning an end of the optical fiber to be in the notch such that the waveguide and the optical fiber are optically aligned.
