Abstract
An electromagnetic radiation detector structure is adapted to detect electromagnetic radiation in at least one first given range of wavelengths centred around a first wavelength λ. The detector structure comprises an absorption region of sub-wavelength thickness configured to absorb electromagnetic radiation, the absorption region having a refractive index n, and a Fabry-Perot cavity housing the absorption region. The disclosure further concerns a method to manufacture the detector structure.
