Abstract
When light is made incident into antenna layers, andof a photodetector, specific wavelength components of light contained in the incident light combine with surface plasmons of the antenna layers, and, and surface plasmon resonance occurs. Thereby, near-field lights are outputted from through-holesof the antenna layers, and. The near-field light outputted from each through-holereaches a light absorbing layervia light receiving surfaces, and. The light absorbing layergenerates a charge of an amount according to the amount of received light. Since cycle intervals Λa, Λb, and Λc of convex portionsin the antenna layers, andare different from each other, the wavelength component of light that combines with a surface plasmon differs in each of the antenna layers, and. Consequently, a plurality of wavelength components of light can be detected.
