10 Gb/s Optical Interconnection on Flexible Optical Waveguide in Electronic Printed Circuit Board

Abstract

<p class="MsoNormal"> <span lang="EN-US">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.</span> </p

Analysis of adhesion strength of laminated copper layers in roll-to-roll lamination process

“…Lamination by R2R was used to deposit graphene electrodes and core layers for the fabrication of solar cells, 3,4 OLEDs, 5 and printed circuit boards (PCBs). 6 The mechanics of laminated composites have been widely studied. The shear lag [7][8][9] and cohesive layer models 10 were proposed to simulate crack and peel-off propagation of the laminated composite.…”
