Visible light communication system at 3.59 Gbit/s based on c-plane green micro-LED

Active tracking system for visible light communication using a GaN-based micro-LED and NRZ-OOK.

Visible light communication (VLC) holds the promise of a high-speed wireless network for indoor applications and competes with 5G radio frequency (RF) system. Although the breakthrough of gallium nitride (GaN) based micro-light-emitting-diodes (micro-LEDs) increases the -3dB modulation bandwidth exceptionally from tens of MHz to hundreds of MHz, the light collected onto a fast photo receiver dr...

LED Modulation Characteristics in a Visible-Light Communication System

This paper conducts a research on modulation characteristics of blue light-emitting diodes (LEDs) used in a visible-light communication (VLC) system. Through analysis of the modulation characteristics of LEDs with different emitting sizes, we find that there is a similar linear relationship between LED’s 3dB bandwidth and the operation current density. This experiment also shows that high serie...

LED-Based Visible Light Communication and Positioning Technology and SoCs

The rapid deployment of high-energy-efficiency, solid-state light emission diode (LED) lighting devices, replacing the conventional luminaires devices, brings unprecedented opportunities for alternative optical wireless communication and navigation applications. This paper reviews the state-of-the-art of LED-based visible light communications (VLC) and positioning (VLP) technologies with a focu...

High - speed visible light communication system based on SiPM

Silicon Photomultiplier (SiPM) is a photodetector with very high sensitivity, fast response and good performance in oversaturation conditions. When SiPM faces incident optical radiation (sometimes imperceptible for other photodetectors) is able to detect very small variations of light. In this work, we present a SiPM-based optical receiver ables to discriminate small light signals from backgrou...
