Board-to-board optical interconnection system using optical slots

Abstract

A practical optical backplane system was prepared with transmitter-receiver processing boards and an optical backplane made of polymeric-waveguide-embedded optical printed-circuit boards. As connection components between the transmitter-receiver processing boards and backplane board, optical slots were used to enable easy and repeatable insertion and extraction of the boards with micrometer precision. We report an 8-Gb/s data transmission between transmitter processing board and optical backplane.
