Transmitter Diversity with Beam Steering [PDF]
2019 21st International Conference on Transparent Optical Networks (ICTON), 2019 Providing high data rates is one of the drivers in visible light communication (VLC) systems. This paper introduces a VLC system that employs transmitters diversity with beam steering to provide high data rates. In this work, red, yellow, green, and blue (RYGB) laser diodes (LD) are used as transmitters to obtain a high modulation bandwidth.

Beam steering of a single nanoantenna
Optics Express, 2020 Nanoantennas play an important role as mediators to efficiently convert free-space light into localized optical energy and vice versa. However, effective control of the beam direction of a single nanoantenna remains a great challenge. In this paper, we propose an approach to steer the beam direction of a single nanoantenna by adjusting two antenna ...
