Optoelectronic module assembly and manufacturing method

An optoelectronic module comprising:

• an active optoelectronic component in or on a mounting substrate, the mounting substrate having a first surface and having a second surface on an opposite side from the first surface;
• an optical sub-assembly;
• a spacer disposed between the mounting substrate and the optical sub-assembly so as to establish a particular distance between the active optoelectronic component and the optical sub-assembly;
• first electrical contacts disposed on the first surface of the mounting substrate;
• and
• second electrical contacts disposed on the second surface of the mounting substrate;
• wherein the first and second electrical contacts are configured to permit active alignment of the active optoelectronic component and the optical sub-assembly.
