Abstract
An optoelectronic component is mounted at a precise position on a waveguide substrate so as to reduce loss in propagating light, and electrically connect electrodes on the waveguide substrate and the optoelectronic component. The waveguide substrate has an optical waveguide and a recessed portion for mounting the optoelectronic component, and electrodes are arranged on the recessed portion. A great number of globular elastic conductive particles are distributed on the bottom surface of the recessed portion. Thereafter, the optoelectronic component is placed in the recessed portion so as to press the globular elastic conductive particles, and alignment between the optical waveguide in the waveguide substrate and an optical waveguide in the optoelectronic component is adjusted. Then, the optoelectronic component is fixed to the waveguide substrate with an optical adhesive while the alignment is precisely adjusted.
