A first surface (108) is formed from a portion of cladding region(107) and a second surface (109) is formed from a portion of core region and a portion of the cladding region. A substrate (104) having electrical tracings (212', 213') is attached to the waveguide (102) so that an electronic component receiving area (111') and an optoelectronic component area (112') are attached to the first and second surface (108, 109) of the waveguide (102) respectively. An electronic component (103) and an optoelectronic component (101) are mounted to the electronic component receiving area (111') and the optoelectronic receiving area (112') respectively.
