Integrated silicon multifunctional mode-division multiplexing system
Optics Express, 2019 Chip-scale optical interconnects have been widely investigated using the wavelength-division multiplexing (WDM) technology, while it has been rarely reported using the mode-division multiplexing (MDM) technology that further improves communication capacity by using multiple spatial mode channels. On the other hand, to achieve large-bandwidth multi-core

DSP complexity of mode-division multiplexed receivers
Optics Express, 2012 The complexities of common equalizer schemes are analytically analyzed in this paper in terms of complex multiplications per bit. Based on this approach we compare the complexity of mode-division multiplexed digital signal processing algorithms with different numbers of multiplexed modes in terms of modal dispersion and distance.
