Photonics for next generation radio access network (RAN)

Masataka Nakazawa

After receiving his Ph.D. from the Tokyo Institute of Technology, Dr. Nakazawa joined NTT Laboratories in 1980. He was a visiting scientist at MIT in 1984. In 2001, he was appointed professor at Tohoku University, where he became the director of the Research Institute of Electrical Communication. He has been a distinguished professor since 2008. He was the president of the Electronics Society of the IEICE, a director at large of the OSA, and a board member of the IEEE Photonics Society. He was the president of the IEICE in 2019. He engaged in research on optical solitons, ultrahigh-speed transmission, and ultrashort pulse lasers that led on from his invention of the compact erbium-doped fiber amplifier (EDFA). His recent research has focused on various approaches to digital coherent transmission, mode-locked lasers, and mobile fronthaul transmission in 5G and 6G. He has published 520 papers and given 400 international conference presentations. He has received many awards including Medal with the Purple Ribbon, the Japan Academic Prize, the IEEE Quantum Electronics Award, the OSA Charles Hard Townes Award, and the Japan Prize. Dr. Nakazawa is a Fellow of the OSA, IEICE (honorary member), JSAP, and a Life Fellow of the IEEE.

The History of Radio Astronomy: celebrating 90 years of innovation and discovery.

Ronald Ekers

Professor Ronald Ekers has had an internationally distinguished career involving research in radio astronomy and radio astronomical techniques. He is a CSIRO fellow, an adjunct Professor at Curtin University in Perth. He has a PhD in astronomy from the Australian National University.
He was appointed Foundation Director of CSIRO's Australia Telescope National Facility and returned to Australia in 1988 after a career in Europe and the US. Previously he was director of the VLA, the largest radio telescope in the USA.
He is a Fellow of the Royal Society, a Fellow of the Australian Academy of Science, the Royal Dutch Academy of Science and the US National Academy of Science. He is also a Foreign Member of the American Philosophical Society.
His research interests in astronomy are broad; including extragalactic astronomy and cosmology, galactic nuclei (the centres of galaxies), ultra high energy particle physics and innovative applications of radio astronomical techniques. He has been heavily involved in all aspects of the International proposal to build a Square Kilometer Array (SKA) since its inception.
Ron is a former President of the International Astronomical Union. In 2003, he received Australia’s prestigious Centenary Medal, and two years later was awarded the Flinders Medal from the Australian Academy of Science. In 2014, he received the Grote Reber Medal for innovative contributions to radio astronomy. He is recognised as an Officer in the Order of Australia.

Dr. Craig J. Rodger holds the Beverly Chair in Physics at the University of Otago in New Zealand. His primary research area is in Space Physics, with a particular focus on energetic electrons trapped in the Earth's magnetic field, termed the Van Allen radiation Belts. Craig's expertise is primarily around the loss of these energetic electrons into the Earth's atmosphere and lower ionosphere through the process of energetic electron precipitation. He has studied this using a mix of space-based and ground-based instruments, including the Antarctic-Arctic Radiation-belt (Dynamic) Deposition – VLF Atmospheric Research Konsortium (AARDDVARK) network, of which he is Co-PI. He helped develop the energetic electron precipitation forcing representation used in the CMIP6 climate modelling improvement effort. The other side of his Space Physics research is in the area of Space Weather, which examines the energy flows from the Sun and how it impacts technological systems on and around the Earth. This has includes ionospheric and atmospheric impacts of solar flares and solar proton events. Most recently he has begun working with the energy industry in New Zealand, investigating the likely impact of extreme space weather on electrical transmission and pipeline networks. This is supported by a large five-year international research project, the Solar Tsunami Endeavour Program: space weather prediction and risk mitigation for New Zealand's energy infrastructure.
