Optical Wireless Communications with Metasurfaces: Current Status and Potential for Intelligent Communications

open access: yesAdvanced Photonics Research, Volume 6, Issue 7, July 2025.
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

open access: yesLaser &Photonics Reviews, Volume 19, Issue 13, July 8, 2025.
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‐

Experimental demonstration of dual‐polarization multiplexed optical phased array empowered by inverse design

open access: yesNanophotonics, Volume 14, Issue 14, Page 2495-2505, July 2025.
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 ...

Comparative Test of Novel Fluorescent Optical Antennas for LED‐ and Laser‐Based Optical Wireless Communications

open access: yesAdvanced Optical Materials, Volume 13, Issue 13, May 5, 2025.
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.
