There is a growing interest in structured light, especially orbital angular momentum (OAM)
beams, due to its unique amplitude and phase structure. Multiple orthogonal OAM beams …

We experimentally demonstrate the enhanced atmospheric turbulence resiliency in a 137.8
Gbit/s/mode mode-division multiplexing free-space optical communication link through the …

In this paper, to achieve higher robustness against atmospheric turbulence for high-capacity
free-space optical (FSO) communications, an adaptive multi-modal FSO transceiver has …

Free-space optical (FSO) communication has gained much interest due to its capability of
providing not only a cost-efficient solution where the optical fiber is too expensive or too …

Multi-plane light converters (MPLC) are a means of deconstructing a wavefront into
constituent modes that are focused at specific spatial locations, and the reverse—that …

For optical wireless communication systems, mechanical beam steering struggles to timely
switch between multiple users or search for moving users. Here we demonstrate a fast-beam …

This paper gives an overview of free space optics applications in terrestrial backhaul. Free
space optics has flexible and fast deployment advantages which serve 5G-A or 6G in space …

Integrated circuits may be important role in future mode-dependent free-space
communications. This presentation will describe broadband optical and THz structures that …
