- Abstract
- We report on the fabrication of a polymer-based 2.5 Gbps x 4 channel optical interconnecting micro-module for optical printed circuit board (O-PCB) application. An optical waveguide array is used for optical transmission from vertical surface emitting laser (VCSEL) array to photodiode (PD) array and the built-in 45 degrees waveguide mirrors are used for vertical coupling. The optical waveguide array and the 45 degrees mirrors are fabricated by UV imprint process in one-step. We fabricate microlensed VCSELs by micro-inkjetting method, which reduced radiation angle of VCSEL from 18 degrees to 15 degrees for better light coupling. We use solder ball array and pin array for alignment between O-PCB and the electrical sub-boards with alignment mismatch below 10 mu m in x, y and z axis. The fabricated optical interconnection module transmits data at the rate of 2.5 Gbps per channel. (c) 2006 Elsevier B.V. All rights reserved.
