Test of mode-division multiplexing and demultiplexing in free-space with diffractive transformation optics [PDF]
, 2016 In recent years, mode-division multiplexing (MDM) has been proposed as a promising solution in order to increase the information capacity of optical networks both in free-space and in optical fiber transmission. Here we present the design, fabrication and test of diffractive optical elements for mode-division multiplexing based on optical ...

Frequency Diversity in Mode-Division Multiplexing Systems [PDF]
Journal of Lightwave Technology, vol. 29, no. 24, pp. 3719-3726,
December 15, 2011, 2011 In the regime of strong mode coupling, the modal gains and losses and the modal group delays of a multimode fiber are known to have well-defined statistical properties. In mode-division multiplexing, mode-dependent gains and losses are known to cause fluctuations in the channel capacity, so that the capacity at finite outage probability can be ...
