発明の名称 (英語) PHOTOELECTRIC TRANSDUCER
発明の概要(英語) Disclosed is a photoelectric transducer (10) provided with a semiconductor layer (13) and a photonic crystal (21) formed in the semiconductor layer (13), wherein the photonic crystal (21) includes nanorods (19) having a lower refractive index than the medium of the semiconductor layer (13) and arranged in the semiconductor layer (13), wherein the nanorods (19) are two-dimensionally arranged at intervals with a pitch of λ/4 or more and λ or less, where λ is the resonance peak wavelength of the photonic crystal (21), and wherein the equation 0.2QV ≤ Qα ≤ 5.4QV is satisfied, where QV is a Q value which is inversely proportional to a coefficient κV indicating the coupling strength between the photonic crystal (21) and the surroundings thereof and which indicates the magnitude of the resonance effect due to the coupling between the photonic crystal (21) and the surroundings thereof, and Qα is a Q value which is inversely proportional to the optical absorption coefficient αa of the medium of the semiconductor layer (13) and which indicates the magnitude of the resonance effect of the medium of the semiconductor layer (13). This increases the optical absorption rate of the photoelectric transducer provided with the photonic crystal structure.
