MUltimode PHotonics for Telecom Applications – MUPHTA

Submission summary

MUPHTA is a 36-month PRCE project that brings together two academic laboratories and a large industrial group to study the fundamental mechanisms of mode coupling and light scattering in few-mode optical fibers (FMFs), candidates for integrating the future high-capacity telecommunications networks using spatial division multiplexing. The view of the MUPHTA project partners is that several upstream aspects of the understanding of mechanisms of losses, mode differential losses and crosstalk remain to be analyzed in order to extract the full potential of FMFs. In this context, the originality of the MUPHTA project lies in the experimental studies it includes (fine analysis of light scattering mechanisms, dynamic measurement of the transmission matrix, measurement of the transmission matrix under a perturbation of the fiber etc.) and whose results will be used to develop empirical and advanced models of the multimode channel that constitutes a FMF in the intermediate coupling regime. The expected benefits of this project are, on the one hand, elements of understanding that will bring keys and guidelines for the proper use of FMFs in a Telecom context and, on the other hand, the effective transfer of knowledge towards the socio-economic environment represented by Draka -Comteq, Prysmian group, a recognized player in the field.
