Power Transmission by Optical Fibers for Component Inherent Communication
Michael Dumke, Gerd Heiserich, Stefan Franke, Lennart Schulz, Ludger Overmeyer
The use of optical fibers for power transmission has been
investigated intensely. An optically powered device combined
with optical data transfer offers several advantages compared
to systems using electrical connections. Optical transmission
systems consist of a light source, a transmission medium and a
light receiver. The overall system performance depends on the
efficiency of opto-electronic converter devices, temperature
and illumination dependent losses, attenuation of the
transmission medium and coupling between transmitter and
fiber. This paper will summarize the state of the art for
optically powered systems and will discuss reasons for
negative influences on efficiency. Furthermore, an outlook on
power transmission by the use of a new technology for
creating polymer optical fibers (POF) via micro dispensing
will be given. This technology is capable to decrease coupling
losses by direct contacting of opto-electronic devices. Full Text
