| Zusammenfassung: | The invention relates to a photodetector (1). In order to provide an improved photodetector, especially for infrared detection, the invention provides that the photodetector comprises a two-dimensional arrangement of resonator-photodiode units (10) disposed along a detector surface (P) for detecting radiation incident from above the detector surface (P) and having a target frequency (νt) that corresponds to a target wavelength (λt) in vacuum, wherein each resonator-photodiode unit (10) comprises a photodiode semiconductor structure (11), which is sensitive to the target frequency (νt), and a subwavelength dielectric resonator (30). |
