Abstract: An optical device including slots and an apparatus employing the optical device are provided. An optical unit device for selectively transmitting electromagnetic waves of a wavelength range, includes a material layer including slots. A gap between the slots has a distance such that the optical unit device has a Q-factor of about 5 or more.
