“…An emerging multiplexing scheme, known as mode division multiplexing (MDM), has been used to transport independent channels simultaneously using eigenmodes [10]. In MDM, eigenmodes are used in MDM to drive the propagation of a number of channels on different modes generated by various mechanisms such as photonic crystal fibers [11], optical signal processing [12,13], few mode fiber [9,14], modal decomposition methods [15,16], laser designs [17,18] and spatial light modulators [19,20]. MDM has been used for switching [21] and for multiplexing [10] in FSO systems.…”

“…Adaptive compensation of the wavefront has been demonstrated for real-time micro-alignment of optics in MDM systems, wavefront tuning and interferometry for wavefront verification in MDM systems in order to improve the output power coupling into the desired mode [6,33,34]. In [35], an SLM is used to calculate phase masks for each mode using a simulated annealing approach which aims to find the most efficient hologram capable of generating a mode with the highest power coupling efficiency based on the MMF profile.…”

“…However, AMI has not been exploited in free-space optical network systems. Another bandwidth-enhancing strategy, known as mode division multiplexing (MDM), is used for enhancing the capacity of free-space optical networks [8][9][10][11][12] by leveraging the abundance of fiber eigenmodes for transmitting various channels by generating specific modes by means of optical signal processing [13][14][15] , spatial light encoding [16][17][18], few mode fibers [19].…”
