Tunable optical structures operating based on slot resonances can be produced with periodic structures where each period includes at least two parallel nanobars with a slot therebetween. The slots include periodic notches served to generate resonances, the wavelength and the quality-factor of which can be controlled by applying bias voltages to nanobars thus generating mechanical movement of such nanobars. Phase modulators with close to unity reflection and beam steering devices can also be made based on these concepts.

Tunable optical metasurfaces based on slot mode resonances

Provided herein are compositions having a porous, architected three-dimensional geometry that are tiled to achieve increased surface area and/or volume. The tiled compositions include a plurality of tiles having seams where one of the plurality of tiles contacts an adjacent tile. Also provided herein are methods and systems for making the compositions.
