Alignment-free injection-molded plastic modules for free-space optical interconnection

We propose a solution to this packaging and alignment problem by using low-cost, injection-molded plastic optical multichip modules (OMCM). This OMCM is a complete hybrid integration of optical, optomechanical, optoelectronic, and electronic components in a self-aligned single platform. The module integrates microlenses, beam-splitting surfaces, and module-to-module connectors and spacers and has room for integrating the optoelectronics devices directly on it.
