In this webinar hosted by the OSA Optics in Digital Systems Technical Group, Dr. Nan Chi of Fudan University and Prof. Zabih (Fary) Ghassemlooy of Northumbria University will provide attendees with an overview of visible light communications, features, issues and what has been done so far. This emerging green technology is exciting and can be used in a number of application, including providing high-speed Internet in homes, offices, etc. as well as indoor localization and sensing.

As a new model that combines lighting and optical communication, visible light communication (VLC) has great market potential. It not only conforms to the national strategic for energy conservation and emission reduction, but also promotes the development and technological advancement of next-generation lighting and access networks. At the same time, with the development of light emitting diode (LED) technologies, LED has gained overwhelming applications in various fields, including lighting, TV and backlight board screen, display etc. In comparison with the traditional incandescent and fluorescent light bulbs, LEDs offer long life-space, much higher energy efficiency, high performance cost ratio and above all very fast switching capability, making VLC one of the hot topics of international competition.

Visible light communication has a wide range of applications, such as indoor and outdoor information networks, ubiquitous 3D positioning/navigation systems and specific safety networks. This presentation summarizes our latest achievements in visible light communication, introducing the emerging components of LED visible light communication, technologies and applications, including novel devices and components in VLC, high-speed underwater VLC system, the pre/post equalization based on machine learning, single-carrier CAP modulation formats, single-carrier Nyquist pulse shaping and DMT bit loading, spatial multiplexing and wavelength multiplexing.
