Abstract
There is provided an optical modulator capable of electrically controlling intensity of transmitted light in a desired wavelength range at a high speed and reducing the size of a device containing the optical modulator. The optical modulator includes a first electrode; a second electrode; and a dielectric layer provided between the first and second electrodes. At least one of the first electrode and the second electrode comprises at least one layer of graphene. There are also provided an imaging device and a display apparatus each containing the optical modulator.
