Flat Optics: Components to Systems

27 June 2021 – 01 July 2021 OSA Virtual Event - Eastern Time (US & Canada) (UTC - 05:00)

An emerging approach is to control incident light’s amplitude, phase, polarization etc. by nanostructures rather than bulky glasses. This spurs the nascent field of flat optics and metasurfaces: a multidisciplinary field that links nanophotonics and optical design.

The scope of this topical meeting is to provide a platform for increasing interaction between researchers with nano- or macro-optics expertise for high-end multifunctional optical components.

This topical meeting will begin from the fundamentals, design and simulation to manufacturing, then shift to device and system levels followed by discussions of practical applications. 

Advanced topics on the simulation and design of flat optical devices using inverse design and machine learning will be discussed in a coordinated effort with the Freeform Optics conference.

Other topics that will be discussed are advanced large-scale manufacturing active and tunable devices as well as flat optical devices for long wavelength regions. Emerging applications of flat optical and metasurface components in systems (displays, Lidar, depth sensors, augmented and virtual reality, communications etc.) will also be discussed.

History of Interferometric Optical Testing

This talk will trace the history of the use of interferometry in testing optical components and optical systems. Early interferometers will be discussed, and special emphasis will be given to the enhancements provided by the use of lasers, electronics and computers.

About the Speaker

James C. Wyant is professor emeritus and Founding Dean at the College of Optical Sciences at the University of Arizona, where he was Director (1999-2005), Dean (2005-2012), and a faculty member since 1974. He received a B.S. in physics from Case Western Reserve University and M.S. and Ph.D. in optics from the University of Rochester. He was a founder of the WYKO Corporation and served as its president and board chairman from 1984 to 1997 and he was a founder of the 4D Technology Corporation and served as its board chairman from 2002 to 2018. Wyant is a member of the National Academy of Engineering, the National Academy of Inventors, and a Fellow of OSA and SPIE. He is a former editor-in-chief of the OSA journal Applied Optics and he was the 2010 president of OSA and the 1986 president of SPIE.

Freeform Optics for Illumination and Imaging: Quite a Ride, and Still a Long Way to Go

In the decades since nodal aberration theory, the basis of freeform imaging optics, was found, and the problem of tailoring freeform optics for illumination was first solved for point sources, freeform optics has developed into a semi-mature state: Used in many products, but not fully understood – routinely manufactured, but hard to tolerance. Some key pieces of theoretical understanding, accessible design methods, and reliable yet affordable manufacturing processes still wait to be discovered.

About the Speaker

Julius Muschaweck, a physicist, is the owner and CEO of his company, JMO. After receiving his M.D. from the Ludwig-Maximilians-University in Munich, Germany in 1989 and a stay as Visiting Scholar at the University of Chicago, he co-founded and ran OEC, a unique combination of optical engineering service and pioneering freeform optics research institute. In 2006, he moved on to OSRAM, where he became Senior Principal Key Expert for Optical Design, and in 2013 joined ARRI, the maker of professional movie cameras and lamp heads, as Principal Optical Scientist. He is Senior Member of OSA, authored over 25 scientific papers and is the inventor of over 50 patents. Throughout his career, his work focuses on applying the theory of thermodynamics of light to everyday problems in illumination optics. Since 2018, he is again a freelance scientist, helping companies to understand and solve their problems in illumination optics, and teaching courses to engineers in industry on how to find good optical designs based on insights from both first principles and practical experience.
