OFC 2020 • 8–12 March 2020 21 Payne has made numerous leading contributions to many diverse fields of photonics and is widely acknowledged as an inventor of key components. With US funding, he led the team that broke the kilowatt barrier for fiber laser output to international acclaim and now holds many other fiber laser per- formance records. An original member of the Highly Cited Researchers (USA) he is honored as one of the most referenced, influential researchers in the world. He has published over 650 Conference and Journal papers. As an entrepreneur Payne’s activities have led to a cluster of 11 photonics spin out companies in and around Southampton - helping to boost the local economy. He founded SPI Lasers PLC, which has been purchased by the Trumpf Corporation of Germany for $40M. He is an Emeritus Chairman of the Marconi Society and a foreign member of the Russian Academy of Sciences. Payne is a fellow of the Royal Society, The Optical Society and the Royal Academy of Engineering. In addition he has been awarded the top American, European and Japanese prizes in photonics. Awards include the John Tyndall Award in 1991, the Marconi Prize in 2008 and the 2007 IEE Photonics Award the first to be awarded to a person outside the USA. In 2010, Payne received the AILU (Association of Laser Users) Award for his pioneering work with fiber lasers. In 2018, he was elected as a Foreign Fellow of the Indian National Science Academy. He became a Commander of the British Empire in 2007 and knighted in the 2013 New Years Honors list. Plenary Session

36 OFC 2020 • 8–12 March 2020 OFC 2020 • 8–12 March 2020 37 Explanation of Session Codes

M1C.4

Day Of The Week Number S = Sunday (Presentation order M=Monday within the session) T=Tuesday W=Wednesday Th=Thursday Session Designation Series Number (alphabetically) 1 = First series of sessions in day 2 = Second series of sessions in day

The first letter of the code denotes the day of the week (Sunday=Sunday, Monday=M, Tuesday=T, Wednesday=W, Th=Thursday). The second element indicates the session series in that day (for instance, 1 would denote the first parallel sessions in that day). Each day begins with the letter A in the third element and continues alphabetically through a series of parallel sessions. The lettering then restarts with each new series. The number on the end of the code (separated from the session code with a period) signals the position of the talk within the session (first, second, third, etc.). For example, a presentation coded M1C.4 indicates that this paper is being presented on Monday (M) in the first series of sessions (1), and is the third parallel session (C) in that series and the fourth paper (4) presented in that session.

What are the research priorities beyond more capacity? For instance, ultra-low latency transmis- sion is increasingly gaining importance in access networks for emerging time critical services. More deterministic and reliable access networks architec- tures, and even new ODNs, are being demanded. Network virtualization, and more intelligent operation and resilience in access networks, also at- tract more and more interest.

This panel will provide a forum for a wide range of speakers to share their ideas on what is important in next- generation access networks. Speakers will discuss what key innovations are needed, beyond additional capacity, and the drivers behind those needs.
