From Inverse Design to Implementation of Practical (quantum) Photonics

Combining state of the art optimization and machine learning techniques with high speed electromagnetic solvers offers a new approach to “inverse” design and implement classical and quantum photonic circuits with superior properties, including robustness to errors in fabrication and environment, compact footprints, novel functionalities, and high efficiencies. We illustrate this with a number of demonstrated devices in silicon, diamond, and silicon carbide, with applications from optical interconnects to on chip laser driven particle accelerators and quantum circuits.

Jelena Vuckovic (PhD Caltech 2002) is a Jensen Huang Professor in Global Leadership, Professor of Electrical Engineering and by courtesy of Applied Physics at Stanford, where she leads the Nanoscale and Quantum Photonics Lab. She is also the director of the Q-FARM: the Stanford-SLAC Quantum Initiative. Vuckovic has received numerous prizes including the IET AF Harvey Prize, Distinguished Scholarship from the Max Planck Institute for Quantum Optics, Humboldt Prize, Hans Fischer Senior Fellowship, DARPA Young Faculty Award, Presidential Early Career Award for Scientists and Engineers, and the Office of Naval Research Young Investigator Award. She is a Fellow of the APS, OSA, and IEEE.

Marin Soljacic


New Physics from Photonic Systems

Nanophotonics offers unprecedented opportunities to mold the flow of light: novel material-systems can thus be implemented in which laws of physics can be tailored almost at will. I will describe this on a few recent examples from our work: non-Abelian topology, new framework for understanding nanoplasmonics, and AI in photonics.

About the Speaker

Marin Soljacic is a Professor of Physics at MIT. He is a founder of WiTricity Corporation (2007), LuxLabs (2017), and Lightelligence (2017). His main research interests are in artificial intelligence as well as electromagnetic phenomena, focusing on nanophotonics, non-linear optics, and wireless power transfer. He received numerous awards for his work, including: the Adolph Lomb medal from the Optical Society of America (2005), the TR35 award of the Technology Review magazine (2006), MacArthur fellowship “genius” grant (2008), Blavatnik National Award (2014). In 2011 he became a Young Global Leader (YGL) of the World Economic Forum.

2020 Symposia and Special Programming

An Interactive Tutorial on Optimization and Machine Learning for Nanophotonics

Tuesday, 14 July, 12:30 - 14:00

Workshop Presenter:
Jonathan Fan, Stanford University, USA

Inverse design algorithms are essential to pushing the performance limits of photonic systems.  In this interactive tutorial, we will discuss two emergent classes of inverse design.  The first is topology optimization based on the adjoint variables method, and we will discuss its mathematical framework and its application to metasurfaces.  The second is machine learning approaches to optimization, and we will give a detailed overview of discriminative neural networks, which can serve as surrogate electromagnetic solvers, and generative neural networks, which can learn and optimize fine geometric features in complex freeform structures.  We will have plenty of time for questions throughout and include demonstrations, where we will show how to execute these algorithms in practice.  If you would like to actively follow these demonstrations, please download the “GLOnets” and “Metagrating Topology Optimization” software packages at:
