ABSTRACT

Future Perspectives in Visible Light Communications

The use of Internet, video and audio calls at a very low cost is now common for all people around the world. This implies a tremendous carrying capacity for the carrier wave. The credit gets back to the use of light as a carrier wave, leading to Optical Communications.

A renewed interest in optical communication was stimulated in the early 1960s with the invention of the laser, considering it as a single frequency source. This device provided a powerful coherent light source, together with the possibility of modulation at high frequency. Many studies were conducted to depict the best carrier wavelengths to be used in optical fiber communications.

In addition to optical fiber communications, the wireless optical communications shared the revolution of optical communications in both outdoor and indoor applications. This was achieved using visible light, leading to Visible Light Communications (VLC). Some of VLC applications include under water communication, vehicle to vehicle communication, indoor broadcast system for internet use and inside airplane communication. In indoor applications, the light emitting diodes (LEDs) are used for dual purposes: illumination and communications.
