Abstract
The present invention relates to a photodetector for detecting an infrared-light emission having a given wavelength (λ) comprising a multilayer with: a layer () of a partially absorbent semiconductor; a spacer layer () made of a material that is transparent to said wavelength; and a structured metallic mirror (), the distance (g) between the top of said mirror and said spacer layer being smaller than λ and said mirror comprising a network of holes defining an array of metallic reliefs with a pitch P of between 0.5 λ/nSC and 1.5 λ/nSC, where nSC is the real part of the refractive index of the semiconductor, a relief width L of between 9P/10 and P/2 and a hole depth h of between λ/100 and λ/15.
