Caption

This is a schematic showing the ultra-thin meta-lens. The lens consists of titanium dioxide nanofins on a glass substrate. The meta-lens focuses an incident light (entering from bottom and propagating upward) to a spot (yellow area) smaller than the incident wavelength. Small meta-lens at the side (red color) showing a different view of the meta-lens.
