Abstract: A photodetector may have a structure including conductive patterns and an intermediate layer interposed between the conductive patterns. A length L of at least one side of the second conductive pattern that overlaps the first conductive pattern and the intermediate layer satisfies the equation L=λ/2neff, wherein the neff is an effective refractive index of a surface plasmon waveguide formed of the first conductive pattern, the intermediate layer, and the second conductive pattern during a surface plasmon resonance. Heat generated in the intermediate layer when the electromagnetic wave having the wavelength λ is incident thereon generates a current variation.

A length L of at least one side of the second conductive pattern that overlaps the first conductive pattern and the intermediate layer satisfies the equation L=λ/2neff, wherein the neff is an effective refractive index of a surface plasmon waveguide mode by a surface plasmon resonance formed of the first conductive pattern, the intermediate layer, and the second conductive pattern. Heat generated in the intermediate layer when the electromagnetic wave having the wavelength λ is incident thereon generates a current variation.
