摘要： A multi-stack graphene structure includes a graphene stack that includes graphene layers including amorphous graphene and thin film dielectric layers. The graphene layers include amorphous graphene. The graphene layers and the thin dielectric layers are alternately stacked on one another. The multi-stack graphene structure also includes an electric field former configured to apply an electric field to the graphene layers.

摘要： An optical device and an optical system including the optical device are provided. The optical device may include a reflective layer and a plurality of nano-beams spaced apart from the reflective layer. The plurality of nano-beams may be formed as a metasurface. The nano-beams may have a pattern structure having a plurality of metasurface forms, and the distance of the gaps between the plurality of nano-beams and the reflective layer may be adjustable individually or as a whole. The optical device may be a beam steering device or an optical phase modulator.
