Joint Spatial Division and Multiplexing for mm-Wave Channels

IEEE Journal on Selected Areas in Communications, 2014
Massive MIMO systems are well-suited for mm-Wave communications, as large arrays can be built with reasonable form factors, and the high array gains enable reasonable coverage even for outdoor communications.

Spatial and Polarization Division Multiplexing Harnessing On‐Chip Optical Beam Forming

Laser & Photonics Reviews, 2023
AbstractOn‐chip spatial and polarization multiplexing has emerged as a powerful strategy to boost the data transmission capacity of integrated optical transceivers. State‐of‐the‐art multiplexers require accurate control of the relative phase or the spatial distribution among different guided optical modes, seriously compromising the optical ...

Compact spatial multiplexers for mode division multiplexing

Optics Express, 2014
Spatial multiplexer (SMUX) for mode division multiplexing (MDM) has evolved from mode-selective excitation, multiple-spot and photonic-lantern based solutions in order to minimize both mode-dependent loss (MDL) and coupler insertion loss (CIL). This paper discusses the implementation of all the three solutions by compact components in a small footprint.
