LMI Seminar: Nanoplasmonic and nanophotonic active devices
Prof. Uriel Levy, The Hebrew University of Jerusalem
Abstract:
We present our recent results related to active nanoplasmonic and nanophotonic devices. Several mechanisms for implementing active devices will be discussed. We will describe the demonstration of tunability in dielectric and metallic metasurfaces for diverse applications using tunability mechanism such as MEMS technology integrated with metasurfaces and the electro optic effect in lithium niobate integrated with metasurfaces, as well as the tunability of a metasurface by controlling an external medium. We also discuss the role of nanoscale structures in enhancing functionalities such as light emission and light detection. Nanophotonic devices with memory functionality will be discussed as well. Finally, we present how metalenses can be used for 3-D imaging.
