By replacing the transparent electrode of the existing image sensor with the electrode of an interferometer structure, the research team enabled the image sensor to perform both the roles of electrode and color filter and succeeded in developing an image sensor prototype by applying this.

The research team applied the permeation of light in certain wavelength through the multiple interference in the interferometer structure. By adjusting the components and thickness of the interferometer electrode in particular, the team increased the color selectivity of Red (R) / Green (G) / Blue (B) without sacrificing electric conductivity.
