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.
