Metamaterials (MM) provide for new ways of manipulating light and achieving complex functionality due to the ability to control the spatial distribution of the permittivity and permeability. This full functionality usually requires complex 3D assemblies of subwavelength resonators that are very difficult to implement at optical frequencies. In this talk I will give an overview of our activities related to 3D metamaterials in the infrared, using both metallic and non-metallic (dielectric) approaches. In the second half of the talk, I will present recent results on the strong coupling between Metamaterials and other dipolar excitations, such as phonons, free carriers and intersubband transitions. Some of these effects can be further exploited for active control of Metamaterials and provide the foundation for new photonic devices in the infrared.
Dr. Igal Brener is a Principal Member of Technical Staff at Sandia National Laboratories (since 2004) and Nanophotonics Thrust leader for the DOE Center for Integrated Nanotechnologies (CINT). He holds a B.Sc. degree in Electrical Engineering (1983), B.A. in Physics (1983), and a D.Sc. degree in Physics (1991), all from the Technion. He worked at Amersham Biosciences/GE Healthcare (2002-2004), in several cell-based and DNA biophotonics projects. From 2000 until 2002 he was with Tellium, Inc. where he worked in optical MEMS switching. From 1991 until 2000 he worked at Bell Laboratories (Murray Hill and Holmdel, NJ) in the Optical Physics Research Department, performing research in ultrafast lasers and spectroscopy of semiconductors, Terahertz phenomena, fiber optical communication, nonlinear lithium-niobate waveguide devices, gallium-nitride lasers and semiconductor heterostructures. During that period, he also advised a number of Ph.D. and master students from NJIT, Stanford, Technion, etc. and served on the advisory board of other startups. Before his research career, he worked as a VLSI engineer at National Semiconductor in their first 32-bit microprocessor development team. He is a fellow of the Optical Society of America, holds 14 patents and has over 90 refereed publications and a similar number of conference presentations. His main current projects are in the area of Plasmonics and Metamaterials, Solid State Lighting (nitride heterostructures) and Nanophotonics in general.
