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 ...

Robust Connectivity in 6G Enabled Indoor VLC Networks Using Intelligent Reflecting Surfaces
IET Communications, Volume 19, Issue 1, January/December 2025.Visible light communication (VLC) in 6G optical networks offers high data rates with extended network coverage. The challenge is that these VLC networks are susceptible to signal obstructions that lower line‐of‐sight (LoS) link quality. This paper proposes a novel framework that uses Intelligent reflecting surfaces, which provide improved non‐LoS ...
