Abstract
Some embodiments of the present disclosure relate to an optical sensor. The optical sensor includes a first electrode disposed over a semiconductor substrate. A photoelectrical conversion element, which includes a p-type layer and an n-type layer, is arranged over the first electrode to convert one or more photons having wavelength falling within a predetermined wavelength range into an electrical signal. A second electrode is disposed over the photoelectrical conversion element. The second electrode is transparent in the predetermined wavelength range. A color filter element, which is made up of plasmonic nanostructures, is disposed over the second electrode.
