Demonstration of 2.5Gb/s optical interconnection using 45/spl deg/-ended connection blocks in fiber- and waveguide-embedded PCBs

A simple method for fabricating fiber- and waveguide-embedded boards for optical interconnects is described. It is quite cost effective and fully compatible with conventional PCB processes. On-board optical link of 2.5Gb/s signals between the transmitter and the receiver modules. was demonstrated by placing connecting blocks having 45/spl deg/-mirror planes at the ends of the fiber and waveguide-embedded boards.
