Visible Light Communications via Intelligent Reflecting Surfaces: Metasurfaces vs Mirror Arrays
نویسندگان
چکیده
We propose two types of intelligent reflecting systems based on programmable metasurfaces and mirrors to focus the incident optical power towards a visible light communication receiver. derive required phase gradients for metasurface array reflector orientations each mirror in achieve focusing. Based which, we irradiance expressions detector plane characterize their performance terms aiming focusing capabilities. show analytically that number elements along with relative source - dimensions determine system capability. Moreover, quantify received gain compared reflector-free systems. In addition, introduce new simple metric assess reflectors' given source, detector, layout. Finally, verify analytical findings regarding absolute via numerical simulations.

Visible Light Communications
Visible light communication (VLC) is an optical wireless communication technology that uses low-power light-emitting diodes (LEDs) to not only provide light, but also broadcast data [1–3]. LEDs are extremely energy-efficient and are expected to become widespread in general lighting applications. Because LEDs are solid-state lighting devices, they can be modulated at high speed compared to other...
متن کامل"Lights-off" visible light communications
– In order to implement visible light communications (VLC) through indoor lighting, a set of challenges arise due to conflicting requirements from the two missions. In this paper we examine one of these challenges: how to communicate when the lights are " off. " We investigate VLC with limits on transmit power, which we define to be low enough so that users will accept that the lights are in th...
متن کاملNanophotonic Visible Light Phased Arrays
Previously demonstrated integrated optical phased arrays have primarily been implemented in silicon-based platforms and have therefore been limited to operation at infrared wavelengths, where silicon provides low-loss transmission. Developing integrated optical phased arrays for visible wavelengths would enable the exploration of new applications for this technology, such as autostereoscopic di...
متن کاملOptical Adaptive Precoding for Visible Light Communications
Multiple-input multiple-output (MIMO) techniques have recently demonstrated significant potentials in visible light communications (VLC), as they can overcome the modulation bandwidth limitation and provide substantial improvement in terms of spectral efficiency and link reliability. However, MIMO systems typically suffer from inter-channel interference, which causes severe degradation to the s...
