The CLEO Plenary Sessions
Nader Engheta, University of Pennsylvania, USA
Materials are often used to control and manipulate photons. Metamaterials and metasurfaces are two representative classes of judiciously designed structures that provide unprecedented platforms for sculpting waves and fields. Their extreme properties lead to novel opportunities in photonics. Light-matter interaction in metastructures exhibits unusual functionalities with numerous exciting features and potential applications.
Biography: Nader Engheta is the H. Nedwill Ramsey Professor at the University of Pennsylvania. He received his PhD from Caltech. His current research activities span various areas of nanophotonics, metamaterials, nano-optics, electrodynamics, graphene optics, optical circuits, imaging and sensing inspired by eyes of animal species, and physics and engineering of light-matter interaction. His most recent awards include William Streifer Scientific Achievement Award, SPIE Gold Medal, Fellow of US National Academy of Inventors, Vannevar Bush Faculty Fellow Award, IEEE Electromagnetics Award, and URSI Balthasar van der Pol Gold Medal. He is a Fellow of OSA, APS, MRS, SPIE, IEEE, URSI, and AAAS.

Listening to Light: Advances in Optoacoustic Imaging
Optical imaging is unequivocally the most versatile and widely used visualization modality in the life sciences. Yet it has been significantly limited by photon scattering, which complicates imaging beyond a few hundred microns. Progress with fast tunable lasers, spectral techniques and advanced instrumentation have allowed the development of multi-spectral opto-acoustic tomography (MSOT) for clinical use, offering unprecedented optical imaging performance and assessment of disease pathophysiology. The talk illuminates progress with optoacoustic macroscopy and mesoscopy and its implication toward clinical impact.
Vasilis Ntziachristos is Professor of Medicine, Professor of Electrical Engineering and Director of the Chair for Biological Imaging (CBI) at the Technical University of Munich, Director of the Institute for Biological and Medical Imaging (IBMI) at the Helmholtz Zentrum Munchen and Director of Bioengineering at the Helmholtz Pioneering Campus. He has received the Diploma in Electrical Engineering and Computer Science from the Aristotle University of Thessaloniki, Greece and the MSc and PhD degrees in Bioengineering from the University of Pennsylvania in Philadelphia. Prior to his current appointment he served as faculty at Harvard University and the Massachusetts General Hospital.
Jian-Wei Pan, University of Science and Technology of China, China
Global Quantum Communication Network and Future Aspects
Based on state of the art fiber technologies, the prevailing quantum communication technology allows practical communication in the metropolitan area. However, the distance of fiber-based quantum communications is limited due to intrinsic fiber loss. To overcome these problems, we are taking two paths in parallel: quantum repeaters and through satellite, to establish a global quantum communication network.
Jian-Wei Pan obtained his PhD degree of Experimental Physics from the University of Vienna in 1999. In 2001, he was appointed as full professor of physics by the University of Science and Technology of China (USTC). In 2011, he was elected as the academician of Chinese Academy of Sciences (CAS). In 2012, he was elected as the World Academy of Science (TWAS) Fellow. His research focuses on quantum optics, quantum information and quantum foundations. He has accomplished a series of profound achievements in experimental quantum information science. Due to his numerous progresses on quantum communication and multi-photon entanglement manipulation, quantum information science has become one of the most rapidly developing fields of physical science in China in recent years.
Sara Seager, Massachusetts Institute of Technology, USA
Mapping the Nearest Stars for Habitable Worlds
For thousands of years people have wondered, “Are there planets like Earth?” “Are such planets common?” “Do any have signs of life?” Today astronomers are poised to answer these ancient questions, having recently found thousands of planets that orbit nearby Sun-like stars, called “exoplanets”. The talk will share the latest advances in this revolutionary field.
Sara Seager is a planetary scientist and astrophysicist at the Massachusetts Institute of Technology. She has pioneered many research areas in the characterization of exoplanets. Her present research focus is on the search for life by way of exoplanet atmospheric “biosignature” gases. She works on space missions for exoplanets including as: the PI of the CubeSat ASTERIA; the Deputy Science Director of the MIT-led NASA Explorer-class mission TESS; and as a lead of the Starshade Rendezvous Mission (a space-based direct imaging exoplanet discovery concept under technology development) to find a true Earth analog orbiting a Sun-like star. Among other accolades, she was elected to the US National Academy of Sciences in 2015 and is a 2013 MacArthur Fellow.
International Day of Light Presentation
John C. Mather, NASA's Goddard Space Flight Center, USA
Exploring the Universe at the Speed of Light
Astronomers travel the universe with imagination and observation, and most of the information arrives as light waves, showing the distant universe as it was when the light was sent out. We can now see at wavelengths ranging from over 10 meters to less than a picometer, limited only by our ingenuity and the opacity of our environment. We are beginning to learn the story of our own origins, from the expanding early universe (mislabeled as the Big Bang), to the formation of galaxies, stars, and black holes, to the stellar nuclear processes producing the heavy elements of life, to the formation of planets that can host life like our own. That history is full of catastrophic events, apparently necessary for our own existence. I will show some of the key discoveries, discuss the expanding universe, and outline the technology that will lead us to deeper understanding. Are we alone? Or put another way, where are the neighbors, and how far away are they? Now that we know planets are common, and about 15% of stars have planets of the right size and temperature to resemble Earth, we can contemplate the direct search for extraterrestrial life through astronomy. In a few decades of serious optical effort, we could know an answer.
John C. Mather is a Senior Astrophysicist in the Observational Cosmology Laboratory at NASA's Goddard Space Flight Center (GSFC). His research centers on infrared astronomy and cosmology. As an NRC postdoctoral fellow at the Goddard Institute for Space Studies, he led the proposal efforts for the Cosmic Background Explorer (74-76), and came to GSFC to be the Study Scientist (76-88), Project Scientist (88-98) and also the Principal Investigator for the Far IR Absolute Spectrophotometer (FIRAS) on COBE. He showed that the cosmic microwave background radiation has a blackbody spectrum within 50 ppm. As Senior Project Scientist (95-present) for the James Webb Space Telescope, he leads the science team, and represents scientific interests within the project management. He has received many awards including the Nobel Prize in Physics, 2006, for his precise measurements of the cosmic microwave background radiation using the COBE satellite.
