95.16-Gb/s Mode-Division-Multiplexing Signal Transmission in Free-Space Enabled by Effective-Conversion of Vector Beams


We introduce a high-efficient vector modes (VMs) conversion scheme by using Q-plate (QP) and half-waveplate based on higher-order Poincaré sphere model. Enabled by this simple mode conversion scheme, we demonstrate a 95.16-Gb/s vector-mode-division-multiplexing (VMDM) transmission with direct-detection orthogonal-frequency-division-multiplexing signal over… (More)
