WDM Based 10.8 Gbps Visible Light Communication With Probabilistic Shaping

4 Gbps direct modulation of 450 nm GaN laser for high-speed visible light communication.

We demonstrate high-speed data transmission with a commercial high power GaN laser diode at 450 nm. 2.6 GHz bandwidth was achieved at an injection current of 500 mA using a high-speed visible light communication setup. Record high 4 Gbps free-space data transmission rate was achieved at room temperature.

Indoor Localization Based on Visible Light Communication

Going beyond 4 Gbps data rate by employing RGB laser diodes for visible light communication.

With increasing interest in visible light communication, the laser diode (LD) provides an attractive alternative, with higher efficiency, shorter linewidth and larger bandwidth for high-speed visible light communication (VLC). Previously, more than 3 Gbps data rate was demonstrated using LED. By using LDs and spectral-efficient orthogonal frequency division multiplexing encoding scheme, signifi...

Visible Light Communication

The visible light communication (VLC) refers to the communication technology which utilizes the visible light source as a signal transmitter, the air as a transmission medium, and the appropriate photodiode as a signal receiving component. The visible light communication technology has a short history compared with other communication technology, for example, public old telephone service, Ether...

Software Defined Visible Light Communication

Software Defined Radio (SDR) has proven to be a practical and effective tool in RF communications, allowing flexible and rapid exploration of dynamic RF signal processing techniques while accelerating advancement of configurable RF antennas and front-end hardware. SDR concepts can be adapted to other physical media; we investigate a Software Defined Visible Light Communications (SDVLC) solution...
