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

open access: yesLaser & 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 ...

Polarization division multiplexing for optical data communications

open access: yesOptical Interconnects XVIII, 2018
Multiple parallel channels are ubiquitous in optical communications, with spatial division multiplexing (separate physical paths) and wavelength division multiplexing (separate optical wavelengths) being the most common forms. Here, we investigate the viability of polarization division multiplexing, the separation of distinct parallel optical ...
