Nanotechnology has enabled the development of nanostructured composite materials (metamaterials) with exotic optical properties not found in nature. In the most extreme case, we can create materials which support light waves that propagate with infinite phase velocity, corresponding to a refractive index of zero. We have developed a variety of in-plane metamaterial designs that permit obtaining a refractive index of zero in the optical regime. We will report on some of the exotic physics of zero-index metamaterials, including strong enhancement of nonlinear optical phenomena, and on flat-bands generated by twisted bilayer photonic crystals.
Bio: Eric Mazur is the Balkanski Professor of Physics and Applied Physics and Area Chair of Applied Physics at Harvard University, Member of the Faculty of Education at the Harvard Graduate School of Education, and Past President of the Optical Society. An internationally recognized scientist and researcher, he leads a vigorous research program in optical physics in the Physics Department at Harvard University. Dr. Mazur has made important contributions to spectroscopy, light scattering, the interaction of ultrashort laser pulses with materials, and nanophotonics. He has also founded several companies and plays an active role in industry.
Dr. Mazur has served on numerous committees and councils, including advisory and visiting committees for the National Science Foundation, and has chaired and organized national and international scientific conferences. He serves as consultant to industry in the electronics and telecommunications industry. In 2006 he founded SiOnyx, a company that is commercializing black silicon, a new form of silicon developed in Mazur's laboratory. Dr. Mazur is currently Chairman of the Scientific Advisory Board for SiOnyx. In 2011 he founded Learning Catalytics, a company that uses data analytics to improve learning in the classroom. In 2013 the company was acquired by Pearson. Mazur is Chief Academic Advisor for Turning Technologies and serves on the Scientific Advisory Panel for Allied Minds, a pre-seed investment company creating partnerships with key universities to fund corporate spin-outs in early stage technology companies.
