Abstract
A graphene optical sensor includes a graphene layer having a surface, a first electrode and a second electrode, formed on the surface of the graphene layer, and arranged in a first direction parallel to the surface of the graphene layer, and a plurality of plasmonic antennas provided on the surface of the graphene layer between the first and second electrodes. Each plasmonic antenna of the plurality of plasmonic antennas, in a plan view, includes a first rod portion extending in a second direction inclined from the first direction, and a second rod portion extending in a third direction inclined from the first direction in a direction opposite the second direction with reference to the first direction, and intersecting the first rod portion. The plurality of the plasmonic antennas is arranged periodically in the second direction and in the third direction.
