Abstract:
The functionalities of traditional optical component are mainly based on the phase accumulation through the propagation length, leading to a bulky optical component such as lens and waveplate. Plasmonic metasurfaces composed of artificial structures have attracted a huge number of interests due to their ability on controlling the optical properties including electromagnetic phase as well as amplitude at a subwavelength scale [1]. They therefore pave a promising way for the development of flat optical devices and integrated optoelectronic systems. In this talk, several research topics for photonic applications based on metasurfaces will be performed and discussed: Beam deflection [2], highly dimensional holographic imaging [3], versatile polarization generation and analysis [4], multi-functional and tunable metadevices [5], achromatic metasurface devices [6] and engineering non-radiating anapole mode in free space [7].
