Visible Light Communication for Wireless Data Transmission

Visible Light Communication (VLC) technology, one of the advanced optical wireless communication technologies, in which light in the visible region (375nm-780nm) is used as a medium for data transmission is more secure and achieves high data rates as compared to conventional wireless technologies like Wi-Fi, Bluetooth, Wi-max etc., which use radio waves for communication. While using wireless i...

Scattering lens resolves sub-100 nm structures with visible light.

The smallest structures that conventional lenses are able to optically resolve are of the order of 200 nm. We introduce a new type of lens that exploits multiple scattering of light to generate a scanning nanosized optical focus. With an experimental realization of this lens in gallium phosphide we imaged gold nanoparticles at 97 nm optical resolution. Our work is the first lens that provides a...

A Survey of Wireless Communication Using Visible Light

This paper introduces the concept of visible light communication (VLC). The urgent need of VLC is to overcome the problems faced in RF communication. Unlike existing methods of wireless communication, the visible light portion of the electromagnetic frequency spectrum is used in VLC to transmit information. This is similar to established forms of wireless communication such as Wi-Fi which uses ...

Secure Wireless Access to a Campus Network

This paper presents a twofold view of campus-wide wireless networks: Users and network managers. Providing an easy network experience to the user while keeping the wireless network secure and manageable is a key issue. This paper presents the description of the vendor-independent approach to a secure wireless local area network being implemented on this university campus. User configuration is ...
