On this paper, a spectrometer design enabling an ultrathin type issue is proposed. Native pressure engineering in group III-nitride semiconductor nanostructured light-absorbing components allows the mixing of a lot of photodetectors on the chip exhibiting completely different absorption cut-off wavelengths. The introduction of a easy cone-shaped back-reflector on the backside facet of the substrate allows …
