Modular Polarization-Engineered Optical Phased Arrays for Optical Wireless Indoor Networks

Abstract

The growing passion for indoor optical wireless networks reflects their immense capability to deliver consistent high-quality data connectivity across diverse indoor environments. This study examines how polarization can be engineered to enhance near-field beam focusing in optical wireless indoor networks using a modular clustered optical phased array aperture. The aperture follows a ceiling-mounted phased array embedded within a phased array layout, associating planar clusters of dipole nano-emitters, supported by a dual-carrier architecture for grating lobe mitigation. We introduce a polarization-adaptive synthesis strategy that determines the cluster-level emitter polarization to replicat..
