Multicore fibers have been intensively studied as an alternative to surpass the performances of conventional fibers. The data transport properties are largely governed by the level of crosstalk and therefore the coupling rate between the cores, which depends on the opto-geometric properties and conditioning of the fibers. During this thesis, you will study experimentally and theoretically the impact of light scattering mechanisms (Rayleigh and extra-losses known as SALS) on differential losses between cores and, above all, on inter-core couplings. The objective will be to evaluate the contribution of light scattering to the total crosstalk observed and to study the possibilities of minimizing it. The work will take in the PhLAM laboratory and will rely on the FiberTech Lille technological platform for fiber manufacturing.
