An optical coupling technique for parallel optical interconnection modules using polymeric optical waveguide films

ParaBIT (parallel inter-board optical interconnection technology) is promising for high-throughput interconnections in advanced switching and computer systems. We have developed a new optical coupling technique for ParaBIT modules using polymeric optical waveguide films. This technique provides good optical coupling in ParaBIT modules, and is also very useful for multi-channel optical coupling. In this paper, we describe the design, structure, and characteristics of this optical coupling technique.
