SENSING WITH MULTIPLE REFLECTIONS IN AN "INFINITE" OPTICAL FIBER
The light in a long optical fiber can behave very strangely. The light
will experience many internal reflections. Especially, if the fiber
is not straight there will be many more internal reflections, more
and more if the fiber is very long and bent.
These reflections influence the final power of the light at the exit of the
fiber. We discovered that this phenomena is unpredictable. The
optical intensity at the exit depends in a chaotic way to the fiber
curvature . We found conditions where the dependence is so strong
that even a tiny nanometer size displacement can result in huge
differences at the exit.
We want to make a mathematical numerical model of this phenomena, to try
to understand and predict the behaviour. We want to collaborate with
small industries to apply this phenomena for a commercial sensor.
For example for sensing small movements, for security application,
military application or engineering applications.
If you are interested in understanding this complex phenomena, if you
like to collaborate with real industries to realize a commerciable
device, please join this research theme.
