Provided is a photodetector including: an organic semiconductor () having protrusions; a metal layer () added onto the organic semiconductor (), for promoting at least one of localized plasmon resonance and surface plasmon resonance in which electrons are excited through irradiation of detection light; and a semiconductor () forming a junction with the metal layer (), for allowing electrons excited through the plasmon resonance to pass through the junction () with the metal layer ().

Photodetector

An organic electroluminescence device, includes a substrate; an anode layer; an organic layer including at least one organic material having a fluorescence spectrum; and a cathode layer, wherein the organic electroluminescence device has a primary light outgoing direction that is parallel to a surface of the substrate, wherein the organic electroluminescence device has an optical waveguide that includes a core layer formed by the anode layer and the organic layer, and a clad layer formed by the substrate and the cathode layer, and wherein the optical waveguide has cutoff wavelengths in a transverse electric mode any one of which is within a wavelength range of a full width at half maximum of the fluorescence spectrum of any one of the organic materials included in the organic layer.
