Abstract
A reflective optical device has an insulation layer, a lattice group, a rear surface electrode, and a voltage application unit. Lattice group is composed of a plurality of lattices including a lattice and a lattice. Each of the plurality of lattices has a structure in which dielectric layer and graphene layer are laminated. Voltage application unit has a function of individually applying a voltage to each of lattice group. Voltage application unit includes a voltage application unit to apply a first voltage to lattice, and a voltage application unit to apply a second voltage to lattice.
