Orbital angular momentum multiplexing three-dimensional encrypted hologram
Acta Physica Sinica<sec>After decades of development, holography has evolved into a sophisticated optical technology for information display. Traditional holographic techniques, which rely solely on the wavelength and polarization of light as information carriers, are limited in both security and capacity of information. The introduction of orbital angular momentum

Orbital Angular Momentum Multiplexing for Optical Fiber Communications
, 2022 Space-division multiplexing (SDM) is a promising technique to further increase the transmission capacity in optical communication systems as the single-mode fiber (SMF)-based systems are approaching their capacity limit. SDM utilizes multiple spatial paths composed of different cores or/and modes as individual channels to transmit data parallelly ...
