Abstract
A meta optical device configured to sense incident light includes a plurality of nanorods each having a shape dimension less than a wavelength of the incident light. Each nanorod includes a first conductivity type semiconductor layer, an intrinsic semiconductor layer, and a second conductivity type semiconductor layer. The meta optical device may separate and sense wavelengths of the incident light.
