Fundamentally the spatial phase of an electromagnetic wave determines its direction of propagation. A natural question therefore arises – how can one control the spatial phase distribution of an electromagnetic wave and thereby its direction of propagation and energy flow? A recent answer to this question relies on the ability to structure the nanoscale coordination of metals and dielectrics across a surface to engineer the interface’s optical response. These engineered surfaces, commonly called metasurfaces, have transformed how we understand the interaction of light and matter and are leading to a revolution in the development optical technology. In this talk I will describe some of our recent work using planar metasurfaces to realize optical elements relevant for spectroscopy and imaging.
Nick Vamivakas studied electrical engineering at Boston University and received his PhD degree in 2008. During this time, he developed high resolution microscopy and spectroscopy techniques to study the electro-optic properties of individual nanostructures. Following his PhD, he was a post-doc from 2007-2011 in the Cavendish Laboratory at the University of Cambridge. Nick joined the Institute of Optics in 2011 and currently is an Associate Professor.
Professor Vamivakas’ research efforts center on light-matter interaction at the nanoscale. He is particularly interested in problems where quantum mechanical effects are pronounced. Potential applications of his research range from optical metrology to quantum information science
