High Bandwidth LiFi Connections with high efficiency data transfers

A unique compound semiconductor structure using VCSELA (vertical cavity surface emitting laser arrays) offers record performance for speed, optical power and low SWaPC. The chip produces low coherent light in a single channel <1mm with ~0.5W and clocked at 25Gbps. The wavelength non coherence has scintillation mitigation properties enabling it to travel farther through the atmosphere. The chip can be produced in high volumes for a low fabrication cost.

Very High Data Rate Optical Wireless Communication with Micro Organic LED

We present a broadband free space light communication using high-speed micro organic light emitting diode (OLED) as transmitter. We report first the design and bandwidth measurements of innovative OLEDs whose size are in the range of tens of micrometres. For OLEDs with reduced active area such as 40 µm x 40 µm, a cut-off frequency up to 345 MHz is reached. Then a free-space optical wireless link is build based on these high-speed micro-OLED. Using Direct Current Optical-Orthogonal Frequency Division Multiplexing) with adaptive bit and energy loading, we achieve a data rate of 2.85 Gb/s.

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.
