Progress in quantum dots for lasers and single photon sources
Institute for Nano-Quantum Information Electronics,
The University of Tokyo, Japan

Since the first proposal of the concept of the quantum dot by Arakawa et al., in 1982, the quantum dots have been intensively investigated for both fundamental solid state physics and device applications. Advances of self-assembling crystal growth technology of quantum dots enabled realization of high performance semiconductor lasers and quantum information devices such as single photon sources. The quantum dots can also be applied to solar cells with a predicted conversion efficiency over 75%. Moreover, implementing a single quantum dot within an optical nanocavity provides a new platform for solid-state cavity quantum electronics (QED).
In this presentation, we discuss progress in quantum dot photonics such as quantum dot lasers and single photon sources. Recent advances in quantum dot cavity-QED are also reviewed.

 European XFEL – New Opportunities for X-ray Science
European XFEL, Germany

The European X-ray Free Electron Laser is the brightest X-ray free electron in the world due to its superconducting accelerator that allows the delivery of up 27000 intense, ultrashort pulses per second. The accelerator started commissioning end 2016. First lasing at hard x-ray energies was observed in May 2017 and the photons systems started commissioning mid-2017. The facility went into operation July 1 2017. First user experiments were started September 14 2017.
It is the world’s first hard X-ray laser facility based on superconducting accelerator technology and will deliver an unprecedented X-ray beam to the user community. The first two instruments open for user experiments are the FXE instrument for ultra-fast x-ray spectroscopy and x-ray scattering and on the SPB/SFX instrument for diffractive imaging and structural determination for single particles, clusters and biomolecules. In 2018/2019 four more instruments will be taken into operation covering a wide range of scientific fields. In the talk a description of the facility will be given including a report of the status of the operation and a glimpse into results from the first experiments.

Robert Feidenhans´l received his Master’s degree in Physics in 1983 and his PhD in 1986 both from the University of Aarhus. He worked as a staff scientist in the Physics Department at Risø National Laboratory from 1986-2001, where he became Head of the Materials Department also at Risø. In 2005 he became professor at the Niels Bohr Institute at University of Copenhagen, where he was vice institute leader 2007-2012 and Head of the Institute 2012-2017. January 2017 he became Managing Director of the European XFEL in Hamburg. Robert Feidenhans’l has been working in the field of X-ray Synchrotron Radiation and Free Electron Laser nearly all his career and has also been Chairman of Council at the European X-ray Radiation Facility in Grenoble and also at European XFEL.

  Topological Photonics and Topological Insulator Lasers
Technion, Israel

The past few years have witnessed the emergence of the new field of Topological Photonics. The first pioneering papers were intended to transfer the concepts of topological insulators from the electronic condensed matter systems to the electromagnetic and photonics settings. This meant transforming fermionic concepts into the bosonic nature of photons. But in the years that followed, many new ideas have emerged, some are universal - making immediate impact of fields beyond photonics, and some are unique to photonic systems. The natural progress in this field is now exemplified by the recent discovery of topological insulator lasers, an idea that started as a quantum simulator and developed all the way to a promising application.

Moti Segev is the Robert J. Shillman Distinguished Professor of Physics, at the Technion, Israel. He received his BSc and PhD from the Technion in 1985 and 1990. After postdoc at Caltech, he joined Princeton as Assistant Professor (1994), becoming Associate Professor in 1997, and Professor in 1999. Subsequently, Moti went back to Israel, and in 2009 was appointed as Distinguished Professor.
Moti's interests are mainly in nonlinear optics, solitons, sub-wavelength imaging, lasers and quantum electronics, although he finds entertainment in more demanding fields such as basketball and hiking. He is a Fellow of OSA and APS. He has won numerous awards, among them the 2007 Quantum Electronics Prize of the EPS, the 2008 Landau Prize (Israel), the 2009 Max Born Award of the OSA, and the 2014 Arthur Schawlow Prize of the APS. In 2011, he was elected to the Israel Academy of Sciences and Humanities, and in 2014 he won the Israel Prize in Physics (highest honor in Israel). In 2015, Moti was elected to the National Academy of Science (USA) as a foreign associate.
However, above all his personal achievements, he takes pride in the success of his graduate students and postdocs, among them are currently 19 professors in the USA, Germany, Taiwan, Croatia, Italy, India and Israel, and many holding senior R&D positions in the industry.
