Abstract
In this paper the irradiance required to transmit up to 1 Gbps to a SiPM using a 405 nm transmitter is compared to the irradiances that could be generated by a transmitter in the exempt group of the standards governing the photobiological safety of lamps and lamp systems. The results that are presented show that existing SiPMs can receive OOK data at rates of up to 900 Mbps at irradiance levels that can be obtained from an exempt LED transmitter operating at 405 nm that covers 28 m2.

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.
