Flexible opto-electrical interconnect module for consumer electronic application

In this paper, we performed a 4 Ch times 2.5 Gbps flexible opto-electrical interconnect module integrated with two silicon optical benchs (SiOBs), four fibers and one rigid-flexible PCB, which provided with capability of optical and electrical data transmission simultaneously. The high-speed data transmission interconnects through fiber, and the electrical transmission interconnects through the circuit of flexible PCB. The SiOB is used for optical coupling between optoelectronics and waveguide, and optical coupling from VCSEL sources to the lightwave circuit is accomplished by 45deg end-mirrors is formed using silicon etching and fibers. A similar optical coupling arrangement is used for the PD array. In this architecture, the assembly tolerances of system are larger than 10 mum. The eye diagram of the electrical output signal from the receiver is tested compliant with SONET OC-48 eye mask.
