1. An image sensor comprising:
a plurality of pixels two-dimensionally arranged, each of the plurality of pixels comprising:
a first meta-photodiode configured to selectively absorb light of a red wavelength band;
a second meta-photodiode configured to selectively absorb light in a green wavelength band; and
a third meta-photodiode configured to selectively absorb light in a blue wavelength band,
wherein a width p of each of the plurality of pixels is less than or equal to a diffraction limit, wherein each of the first meta-photodiode, the second meta-photodiode and the third meta-photodiode has a columnar vertical structure.
