Ultralow Photon Flux OWC Links Using UV‐C Single‐Photon Detection

Laser &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

Nanophotonics, 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 ...
