In this paper, we proposed 10 Gb/s transmission using
4-channel polymer waveguides on the optical electronic printed circuit board.
It was simulated by the ray tracing method for tolerance study of optical
interconnection and fabrication. In order for easy fabrication and high
position accuracy, the polymer waveguides were forming silver coated 45° reflective
mirrors by dicing method and e-beam deposition for 90° light beam turning. The
coupling loss was demonstrated in different polishing grit sizes. The optical
interconnection in board-embed 4-channel flexible waveguides was demonstrated
with a low propagation loss of 0.1 dB/cm and a clear eye diagram at 2.5 Gb/s
data rate per channel.
