Dr. Vijay Vusirikala

Head of Optical Network Architecture and Engineering, Google, USA

10:30 – 11:00     Congress Hall

A Decade of Software Defined Networking at Google

Abstract: Google’s global cloud infrastructure is built on three pillars: ubiquity, disaggregation and high availability. To support these three pillars, we have been building a network unparalleled in reach, scale and capability over the last decade.  Early on, we realized that the network we needed to support our services did not exist and could not be bought. Hence, over the past 10+ years, we set out to fill in the required pieces in-house. Our fundamental design philosophy is that the network should be treated as a large-scale distributed system and leverage the same control infrastructure we developed for Google’s compute and storage systems. In the process, we made every network layer intelligent, fault-tolerant, highly reliable and programmatically manageable to allow for rapid evolution and innovation. Software defined networking is the only way we build network infrastructure at Google today.

Vijay Vusirikala is Head of Optical Network Architecture and Engineering at Google, responsible for technology development, design, scaling and optimization of Google’s optical network covering client optics, campus, metro, long haul and submarine links. His team spurred a number of network innovations and catalyzed early adoption of new optical technologies such as open line systems, Data Center Interconnect (DCI), Subsea Open Cables, C+L band line systems, and programmable transport layer, in a large scale production environment.

Prior to Google, Vijay was Director of Marketing at Infinera where he worked with major global network operators to design and deploy PIC based digital optical networks. Prior to joining Infinera, he was at Motorola Access Networks as Director of Market Development for PON, DSL, and IPTV products. Earlier, he was with Sycamore Networks in senior system architecture and product management roles, where he defined architecture for reconfigurable optical networks, and integrated switching and transport systems.

Vijay has published extensively and holds 15+ patents in optical components, system design and network architecture. He is a frequent speaker at industry conferences and executive forums. He received an MS in Physics and a Ph.D in EE with a focus on optoelectronic integration from the University of Maryland, College Park and a BSEE from IIT, Madras in India


Professor Anne L’Huillier

Division of Atomic Physics, Lund University, Sweden
Member of the Nobel committee for Physics from 2007 to 2015.

11:00 – 11:30    Congress Hall

50 years of Nobel Prizes in Photonics: From 1964 to 2014

Abstract: This presentation will describe some of the Nobel prizes in Physics in the area of Photonics. Starting from the 1964 Nobel prize to Townes, Basov and Prokhorov “for fundamental work in the field of quantum electronics, which has led to the construction of oscillators and amplifiers based on the maser-laser principle” to the 2014 Nobel prize to Akasaki, Amano and Nakamura “for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources”.

Anne L’Huillier is a professor in Atomic Physics at Lund University since 1997. Her research is centered around high-order harmonic generation in strong laser fields and its applications, in particular, to attosecond science. She was elected to the Royal Swedish Academy of Sciences in 2004 and has been a member of the Nobel committee for Physics from 2007 to 2015.


Professor Philip Diamond

School of Physics and Astronomy, University of Manchester, UK
Director-General of the SKA (Square Kilometre Array), UK

11:30 – 12:00     Congress Hall

Square Kilometre Array and how it will be Heavily Reliant on Optical Fibre Systems

Abstract: The Square Kilometre Array, a next-generation radio telescope, will change the way humanity views the Universe. Building on 70 years of radio astronomy developments, astronomers and engineers are designing what will be the largest scientific instrument on the planet. The SKA, currently in the detailed design phase, will be built in Australia and South Africa by an international consortium, currently of 10 nations. The science to be done by SKA encompasses almost the entire history of the Universe, from exploring the so-called Cosmic Dawn, when the first stars and galaxies were formed, to understanding how planets are formed in the present day. Along the way SKA will enable precise studies of the secrets of gravity, dark energy, dark matter and the molecular building blocks of life.

I will discuss the current status of SKA, as the project prepares for the transition to construction. I will describe in detail the critical role that optical fibre systems play in enabling the SKA, with its requirement to transmit data at Tbit/sec rates over hundreds and thousands of kilometres, to become a reality.

Professor Philip Diamond is the Director-General of the SKA (Square Kilometre Array). He was appointed to this position in October 2012, and is responsible for the team designing and ultimately constructing the SKA, which, when completed, will be the largest scientific project on Earth.

From 2010 – 2012 he was the Chief of CSIRO Astronomy and Space Science (CASS), which operates the major radio astronomy facilities in Australia, namely Parkes, the Compact Array and Mopra. CASS also operates the NASA Deep Space Network tracking station at Tidbinbilla, near Canberra, and has built ASKAP, the Australian SKA Pathfinder, in the Murchison in Western Australia.

Prof Diamond moved to Australia in June 2010, leaving his previous role as Director of the Jodrell Bank Centre for Astrophysics, part of the School of Physics and Astronomy at the University of Manchester in the UK. The University owns and operates the giant Lovell Telescope and, on behalf of the UK’s Science and Technology Facilities Council, the e-MERLIN/VLBI National Facility. Prof. Diamond was responsible for the operation of both facilities.

Professor Diamond completed his PhD at the University of Manchester in 1982. He worked at the Onsala Space Observatory in Sweden and the Max-Planck Institute for Radioastronomy in Bonn, Germany before moving to the National Radio Astronomy Observatory (NRAO) in the USA for 12 years. He held the position of Deputy Director of the NRAO’s VLA and VLBA before moving back to the UK in 1999 upon being appointed as the Director of MERLIN.

Professor Diamond’s research interests include studies of star birth and death; exploring both through the use of radio interferometers such as MERLIN. He is also interested in high resolution studies of supernovae, both in our own Galaxy and in others. Finally, he also dabbles in studies of discs of molecular gas rotating around super-massive black-holes at the centres of other galaxies. He has published ~300 research papers in astronomy.

Phil is married to Jill; they have a son who recently graduated with a degree in Biochemistry and Genetics from the University of Leeds and a daughter who works as a project manager for a company installing remote scanning devices in libraries, warehouses and factories. He enjoys reading, supporting Manchester United and the England Rugby and Cricket teams, watching his son play rugby and playing the (very) occasional game of squash.
