An optical interconnection with a new optically transparent polymer called polynorbornene (PNB) was investigated for short-distance and high-speed data transmission on printed circuit boards (PCBs). PNB waveguides were formed by simple photoirradiation followed by heating without development and reactive ion etching (RIE) processes. The PNB waveguides exhibit a high-heat resistance of more than 270 °C and an extremely low optical loss of 0.029 dB/cm at 830 nm. We successfully integrated PNB waveguides into a multilayer PCB, which we call a optical/electrical printed circuit board (O/E-PCB), and confirmed a basic data transmission rate of 10 Gbps.
