A low-cost and small-scale optical engine using passive direct coupling method based on organic substrate technology is proposed and demonstrated in this paper. The design and fabrication of the organic optical bench (OOB) including analysis on optical coupling efficiency and electrical 3-dB bandwidth and fabrication process of organic optical bench is firstly presented. Then the properties of organic substrate are tested. Thermal cycle analysis and vibration are modeled and simulated as well. The simulation results show that stress and strain have little effect on the coupling efficiency and the golden bump joint has good reliability. Finally, the whole optical subsystem assembly process flow is introduced and the corresponding test system is built to verify the performance of the optical engine. Test results show the optical eye diagrams of the four-channel transmitters and electrical eye diagrams of the four-channel receivers are all clearly open enough to support standard 10Gbps data rate. Organic substrate material is seldom studied and applied for optical carrier before, the optical engine proposed in this paper demonstrated its feasibility and potential to be applied in short-reach optical interconnection and high speed applications such as video/audio signals transmission..
