Abstract
A metasurface is capable of modulating input light including a wavelength in a range of 880 nm to 40 μm. The metasurface includes: a GaAs substrate including a light input surface into which input light is input and a light output surface facing the light input surface; an interlayer having a lower refractive index than GaAs and disposed on the light output surface side of the GaAs substrate; and a plurality of V-shaped antenna elements disposed on a side of the interlayer which is opposite to the GaAs substrate side and including a first arm and a second arm continuous with one end of the first arm.
