A green absorbing fluorescent fibre concentrator for VLC.

Amna Riaz, Steve Collins University of Oxford

Abstract
Fluorescent concentrators avoid the trade-off between optical gain and field of view of conventional optical concentrators. Furthermore, they can be created from inexpensive fluorescent fibres which are easily integrated into the edges host systems, including smart phones to create a receiver that supports higher data rates and is more robust to line-of-sight blockage. In this paper results from a system that includes a fluorescent fibre that absorb green, rather than violet light, are presented for the first time. The availability of fibres that absorb different wavelengths means that they can be used to either support wavelength-division multiplexing or to create transceivers that avoid self-interference by transmitting and receiving data with different wavelengths.

The conference focuses on leading edge research on Optical Wireless Communication in its different forms and gathers experts from academia and industry to show their latest technical results and showcase their products and services. The application scope is broad and it ranges from Ultra-short range to Ultra-long range.

Conference topics cover visible light communication, infrared optical and ultraviolet communication. These different forms of OWC can potentially be employed in a diverse range of communication applications ranging from optical interconnects within integrated circuits through outdoor inter-building links to free-space satellite communications.

The following topics are being covered during the conference:

  • Ultra-short range: for instance chip-to-chip communications in stacked and closely packed multi-chip packages
  • Short range: For instance wireless personal area network (WPAN) applications under standard IEEE 802.15.7 and underwater communications.
  • Medium range: indoor IR and visible light communications (VLC) for wireless local area networks (WLANs) and inter-vehicular and vehicle-to-infrastructure communications.
  • Long range: inter-building connections, also called free-space optical communications (FSO).
  • Ultra-long range: Laser communication in space especially for inter-satellite links and establishment of satellite constellations

This paper was presented during the conference which took place during the Photonics Applications Week.
