Specialty fibers exploiting spatial multiplexing for signal processing, sensing and beyond (SYNERGY)


2021 - 2024


Firstly, SYNERGY seeks a novel Spatial Division Multiplexing (SDM) fiber solution for a better optical True-Time Delay Lines (TTDL) performance for microwave signal processing in terms of RF bandwidth, chromatic dispersion range, number of signal samples and robustness against fabrication errors, going beyond our preliminary demonstrations in the field. Furthermore, it will explore the implementation of different optical signal processing functionalities, such as optical sampling or parallel chromatic dispersion compensation. Secondly, SYNERGY project aims at pioneering and developing innovative optical technologies based on specialty SDM fibers to revolutionize the future display of broadband fibers‐wireless communication scenarios. More specifically, the general goal is to exploit the inherent parallelism of multicore fibers, few‐mode fibers and combination of both to implement a variety of signal processing and multiparameter sensing applications featuring unique properties beyond the state of the art in terms of compactness, lightness, system stability, power efficiency, versatility and record bandwidth. Finally, SYNERGY will bring the chance to develop sensors not only with commercially available fibers but also with specialty ones, improving the sensor sensibility and providing novel techniques of interrogation for better requirement benchmarking. We want to explore the incorporation of specially designed cavities not only to use the reflected light, but also to exploit the benefits of retrieving the phase of the signal, while providing a robust design against external interferences. We plan as well to develop structures that will enhance the interaction with the external medium and postprocess the fibers with different coatings and terminations.
