Optoelectronic device and physical layer technology for high-speed underwater wireless optical communications

In recent years, high-speed visible light communications (VLC) have been identified as an essential part of optical wireless communication technologies for next generation 6G network. As one of the fast-growing techniques in VLC, underwater wireless optical communication (UWOC) offers the unique advantages of enabling ultra-high data rate Internet of Underwater Things (IoUT).

Eyes of Tomorrow: Zero-power 3D Passive Imaging via LiFi / VLC infrastructure

Time-of-Flight (ToF) is a rapidly growing field that seeks to improve the capabilities of computer vision applications by emitting photons and reconstructing the scene from the reflected photons. The aim of this work is to revolutionize the field of 3D imaging by introducing a novel approach: passive 3D ToF imaging via Light Fidelity (LiFi) or Visible Light Communication (VLC) technology. State-of-art ToF sensing suffers from high power consumption and thermal drifts caused by built-in illumination sources. Additionally, the background light is treated as a disturbance, unlike in passive imaging modalities.

LiFi in space

LiFi, short for Light Fidelity, is a wireless communication technology that uses visible light instead of radio waves to transmit data. LiFi is based on the principle of Visible Light Communication (VLC), where LED lights are used as transmitters to send data to a receiver, which is typically a photodiode.
