Abstract

Modern high-capacity coherent optical systems rely on wavelength multiplexing and polarization multiplexing to support the efficient transmission of Internet traffic. However, to accommodate the exponential growth of data and prevent rising costs per bit, innovative multiplexing techniques and device integration methods are necessary. In this context, space-division multiplexing (SDM) emerges as a solution by harnessing parallel spatial paths to expand the capacity of optical systems. SDM can be applied through various approaches, such as utilizing bundles of single-mode optical fibers, multicore fibers, multimode fibers, or hybrid few-mode multicore fibers. When transmitting signals through coupled-core multicore fibers or few-mode fibers, channel coupling becomes a concern. Coupled transmission requires digital signal processing (DSP) techniques at the receiver, employing multiple-input multiple-output equalization (MIMO) to retrieve the transmitted information. Although most experimental work on coupled SDM transmission considers that the number of available transmitters and receivers is equal to the number of supported modes, it is very likely that, in systems with a large number of modes, the number of transmitters and receivers will grow progressively as the demand increases. This project aims at characterizing large-count spatial multiplexers and demultiplexers (with up to 6 or 45 modes) for progressively activating channels in an SDM system. The experimental work will be carried out at the facilities of the Optical Networks Group at UCL, led by Prof. Polina Bayvel, which is one of the most respected groups worldwide. The cooperative work will be led by Prof. Filipe Ferreira, who has a large history of collaboration with the research group at Unicamp. The student will get in touch with experimental SDM setups which are not available in Brazil, considerably increasing his understanding of the technology. (AU)
