Abstract
Provided is an optical modulator having high resolution and being capable of controlling a wavelength range of reflected/transmitted light. The optical modulator may include a plurality of nanostructures capable of changing refractive index and a first insulation layer surrounding the plurality of nanostructures. The refractive index of each of the nanostructures may be greater than that of the first insulation layer. The nanostructures may modulate light depending on a change in the refractive index thereof. A change in a resonance wavelength, intensity, phase, polarization, etc. of reflected/transmitted light may be generated.
