Experimental Study of Coherent and Non-Coherent Next-Generation Optical Networks (Phase 3)

This research project focuses on the experimental study of next-generation optical networks, covering both coherent and non-coherent architectures, to address the growing demand for data transfer rates driven by services like the Internet of Things (IoT). The main problem lies in the need to increase the capacity of optical transport networks (PON, metropolitan, and regional) without excessively increasing complexity or cost, especially considering new standards of 25 and 50 Gb/s per wavelength. The proposed solution involves the design, simulation, and experimental demonstration of new transmission and information processing techniques, reusing existing infrastructures. The performance of low-cost techniques such as Intensity Modulation and Direct Detection (IM + DD), as well as low-complexity coherent techniques, will be investigated. The methodology includes an exhaustive state-of-the-art review, mathematical modeling (Matlab, Python), and simulation (Optsim, VPI Photonics), culminating in the implementation of laboratory prototypes. The ultimate goal is to generate experimentally validated knowledge to be disseminated through indexed scientific publications (Scopus, Web of Science) and human talent development (undergraduate, master's, and doctoral theses), contributing to technological advancement in high-speed telecommunication networks.<br/><br/><b>Goal</b>: <br/>To experimentally study next-generation coherent and non-coherent optical networks, aiming to evaluate their performance and propose cost-effective transmission and information processing techniques to increase the capacity of existing infrastructures.<br/><br/><b>Research lines</b>: <br/>New generation telecommunications networks
