Optical wireless communications (OWCs) provide a promising alternative to spectrum‐congested microwave wireless communications. Recently, the use of metasurfaces with sub‐wavelength features for dynamic beam steering, beam manipulation, and spatial or optical‐angular‐momentum mode generation, conversion, and multiplexing in OWCs is proposed and ...

Ultralow Photon Flux OWC Links Using UV‐C Single‐Photon Detection
This work presents ultralow photon flux UV‐C optical wireless communication (OWC) links using a micro‐LED and a silicon photomultiplier (SiPM)‐based single‐photon detector (SPD). A record‐low transmission of 7.7 photons per bit and a maximum data rate of 120 Mbit s−1 are achieved. Furthermore, single‐photon links highlight the potential for a future UV‐

Abstract This paper presents a dual‐polarization multiplexed optical phased array (OPA) implemented on a 220 nm silicon‐on‐insulator (SOI) platform, enabling continuous beam steering across TE and TM modes. While effectively guiding TE‐ and TM‐polarized light, the proposed OPA on this platform faces the challenge of overcoming the intrinsically high ...

New fluorescent optical antennas are realized and tested for diverse Optical Wireless Communication (OWC) applications. The fluorescent concentrator slabs, based on different organic fluorophores, convert and convey the digital data conveyed through intensity modulation of incoming light toward a small‐area photodiode.
