Fibers in Printed Circuit Boards With Passively Aligned Coupling

Several types of printed circuit boards with embedded optical glass fibers for board level optical interconnects are presented. Transmitter and receiver coupling elements were developed which are solder temperature resistant and align passively on the fiber ends of the embedded glass fibers. Further a cost-effective demonstrator system using FPGA, serializer/deserializer, VCSEL driver, and photodiode amplifiers to test the optical interconnect was set up and is described.
