Impact of Device Orientation on Error Performance of LiFi Systems
IEEE Access, 2019 Most studies on optical wireless communications (OWC) have neglected the effect of random orientation in their performance analysis due to the lack of a proper model for the random orientation.

Toward a universal metasurface for optical imaging, communication, and computation
Nanophotonics, Volume 11, Issue 17, Page 3745-3768, September 2022., 2022 Abstract In recent years, active metasurfaces have emerged as a reconfigurable nanophotonic platform for the manipulation of light. Here, application of an external stimulus to resonant subwavelength scatterers enables dynamic control over the wavefront of reflected or transmitted light.

Prototyping and measurements for a LiFi system [PDF]
2016 IEEE Sensor Array and Multichannel Signal Processing Workshop (SAM), 2016 We are witnessing a revolution in wireless technology where Light Fidelity (LiFi) emerges as one potential candidate. In this paper we present a LiFi prototype that allows us to verify the feasibility of deploying this technology. The prototype is based on two Spartan 6 FPGAs and uses a Light Emitting Diode (LED) to transport the information through ...
