Digital transformation and its impact in 5G/Post 5G era
Various activities toward digital transformation have been taking place in such areas as advanced marketing, high level medical image diagnosis and intelligent telecommunication network operations based on bigdata analytics and AI as well as RPA(Robotic Process Automation ) for efficient office work. In other area like automobile industry, the number of connected cars are gradually increased whereas various PoC(Proof of Concepts) experiments of autonomous cars have been carried out not only in automobile manufacturers but also in OTT (Over The Top) players such as Google.
In business fields, cash less economy such as QR code payment has been rapidly expanded in China and its impact has been spread out everywhere like Japan. Sharing economy and subscription model are also new movements all over the world. In the former, people can easily find/put items online they want to use/rent, and they can save/earn some money instantaneously. In the latter, service providers can obtain regular basis revenue whereas customers can enjoy services such as online music at small cost each month.
In this presentation we will discuss how these trends will be accelerated and advanced in the 5G/Post 5G era.

Submarine communications-connecting the world
Undersea fiber optic cables are the integral part of worldwide communications infrastructure carrying more than 99% of international data traffic between continents. In a bit more than last 20 years transmission technology experienced explosive growth resulting in more than 105 orders of magnitude increase in cable capacity and similar reduction in cost per information bit. Despite this progress the demand for communication capacity is far from saturation with current annual growth rate of at least 30%. We are reaching an interesting point in history where transmission technology is becoming very mature and approaching fundamental limits. The talk will examine the evolution of transmission concepts that changed multiple times in the last 20 years, the next immediate steps in technology evolution, further challenges facing continuing capacity growth, and the need for the new disruptive technologies.
Alexei Pilipetskii received his Ph.D. in 1990 for the research in nonlinear fiber optics from Academy of Sciences Russia. From 1994 to 1997 he was with the University of Maryland Baltimore County, where his interests shifted to the fiber optic data transmission. In 1997 he joined Forward Looking team at AT&T Submarine Systems, currently SubCom where he was focused on the transmission research and introduction of the new technologies. He currently leads the transmission research department (Forward Looking Team) at SubCom. He is an author and co-author of more than 200 journal and conference publications, and more than 25 patent applications. He is IEEE Photonics Society Fellow from 2018.

Progress in InP-based photonic integration
The application market for Photonic Integrated Circuits (PICs) is rapidly growing. Photonic Integration is the dominant technology in high bandwidth and long-distance tele-communications and is increasingly applied in shorter distances and within data centers. It is set to become dominant in many other fields of photonics. PICs offer compelling performance advances in terms of precision, bandwidth and energy efficiency. To enable uptake in new sectors, the availability of highly standardized (generic) photonic integration platform technologies is of key importance as this separates design from technology, reducing barriers for new entrants. Another major challenge is low-cost and energyefficient integration of photonics with the electronic circuitry that is used for driving and controlling the photonic IC and processing its information. The major platform technologies today are Indium Phosphide (InP)-based monolithic integration and Silicon Photonics. InP-based technology offers integration of the full suite of photonic components, including lasers, optical amplifiers and highperformance modulators. In this paper we describe the current status and future developments of InP-based generic integration and we discuss the potential of InP-based Photonics for integration with electronics.
Meint K. Smit started research in photonic integration in 1981. He invented the Arrayed Waveguide Grating, a key component in modern WDM systems, for which he received a LEOS Technical Achievement award in 1997. He was closely involved in the introduction of MMI-couplers, which are key components in Photonic ICs. In 2000 he became the leader of the Photonic Integration group at the COBRA Research Institute of TU Eindhoven. His current research interests are in InP-based Photonic Integration and integration of InP circuitry on Silicon. He is the founder of the JePPIX platform, the Joint European Platform for Photonic Integration of Components and Circuits and strongly involved in the development of the InP-based photonic foundry system in Europe. Meint Smit is an IEEE Fellow. In 2012 he received an ERC Advanced Grant and in 2016 the Rank Prize for Optoelectronics.

Flexibly scalable high performance architectures with embedded photonics
Computing systems are critically challenged to meet the performance demands of applications particularly driven by the explosive growth in data analytics. Data movement, dominated by energy costs and limited ‘chip-escape’ bandwidth densities, is a key physical layer roadblock to these systems’ scalability. Integrated silicon photonics with deeply embedded optical connectivity is on the cusp of enabling revolutionary data movement and extreme performance capabilities. Beyond alleviating the bandwidth/energy bottlenecks, embedded photonics can enable new disaggregated architectures that leverage the distance independence of optical transmission. We will discuss how the envisioned modular system interconnected by a unified photonic fabric can be flexibly composed to create custom architectures tailored for specific applications.
