Invariant Properties in Multimode Fibers for Imaging Applications

Contact : Sebastien Popoff

The control of light propagation in optical multimode fibers is an active and fast-growing field of research. Multimode fibers allow different trajectories – or modes – to propagate. Taking advantage of these spatial degrees of freedom would allow increasing significantly the number of channels in optical fiber communication systems by using a MIMO (Multiple-Inputs / Multiple-Outputs) approach. Similarly, researchers investigate the way to control and study light in multimode fibers for their use as a minimally invasive endoscopic imaging device.

However, due to dispersion and randomness in light propagation, the information or image is scrambled upon propagation through the fiber. We propose here to study the invariant properties of multimode fibers to reconstruct information without any prior calibration of the system to allow real-time applications.

The internship will involve primarily experimental work, with also numerical simulations.

This internship can lead to a Ph.D. thesis with partial fundings already available.
