14:00 Keynote talk: Metaoptics for Active Photonics

Metaoptics offer unique opportunities for light control through dispersion engineering and optical nonlinearities. Here we demonstrate ultrashort pulse shaping with metasurfaces and new schemes for spatial light modulation and Gigahertz speed transmission modulation based on Mie resonances and on organic layers with giant electrooptic coefficient.

We present excitation and active modulation of Surface Plasmon Polaritons (SPPs) at degenerately doped PN++- junction based on lattice matched Indium Gallium Arsenide. The device is experimentally characterized, showing far-field voltage assisted reflectivity modulation for mid-IR wavelengths. Numerical simulations of the device have confirmed the experimental findings and predict data rates of up to 1Gbits/s. Decreeing the device physical dimensions can lead to data rates in excess of 50Gbits/s, thus providing a new pathway toward fast plasmotronic devices.

We provide a spin and orbital angular momentum representation of the inverse Faraday effect in a metal. We analytically show the role of the spin and orbital angular momenta of light, as well as the spin-orbit interaction (SOI), in the generation of an optoinduced magnetization. We also show that resonances in plasmonic nanoantennas enhance and confine the IFE, thereby leading to static magnetic fields directly applicable in a vast application domain including all-optical magnetization switching and spin-wave excitation.
