ZrO2 Holographic Metasurfaces for Efficient Optical Trapping in The Visible Range

In this paper, we introduce a new material platform for holographic metasurfaces. Ceramic-based metasurfaces are ideally suited for biophotonic applications, where the operating wavelength goes down to the blue region of the visible range and below. Here, we exploit the unique properties of this platform by demonstrating the first on-chip trapping using blue light.
