Continuous wave Bessel beams with a strong longitudinal acceleration in free space
, 2022 A variety of transversely accelerating optical beams, such as Airy, Mathieu, and Weber beams, have been proposed and intensively studied in the past few decades, while longitudinal acceleration of optical beams in free space has been considered much less

Free-space optical communication employing subcarrier modulation and spatial diversity in atmospheric turbulence channel [PDF]
, 2008 An expression for the bit error rate of a multiple subcarrier intensity-modulated atmospheric optical communication system employing spatial diversity is derived. Spatial diversity is used to mitigate scintillation caused by atmospheric turbulence, which

Multi-element fiber for space-division multiplexed optical communication system [PDF]
, 2014 This paper reviews a novel approach of implementing space-division multiplexing (SDM) based on Multi-element Fiber (MEF) technology. The MEF geometry provides for ultra-low crosstalk between the spatial channels while full compatibility with standard WDM
