Abstract
A photodetector includes a Helmholtz resonator and a photosensitive structure that is placed in an electric-field-concentrating interval forming part of the Helmholtz resonator. Such a photodetector is in particular suitable for imaging applications. The wavelength of the radiation to be detected is determined by dimensions of the Helmholtz resonator, within a detection spectral interval of the photosensitive structure.
