Active and tunable dielectric nanoantennas and metasurfaces (Conference Presentation)

Paper Abstract

Two major trends in dielectric nanoantenna research related to achieving their active and tunable functionalities will be discussed. Interfacing of dielectric nanoantennas with light emitters provides opportunities to enhance their emission and shape its directivity. By making the nanoantennas themselves out of active III-V semiconductor materials, lasing action with controllable directionality can be achieved. On the other hand, by endowing nanoantennas with tuneable properties dynamic control of light wavefront can be achieved pawing way to spatial light modulators with sub-micrometre resolution.
