Abstract

A semiconductor detector () for electromagnetic radiation within a wavelength range is disclosed, comprising a first waveguide portion (), a funnel element () configured to funnel incident electromagnetic radiation into a first end () of the first waveguide portion, and a second waveguide portion () extending in parallel with the first waveguide portion. The second waveguide portion is coupled to the first waveguide portion and configured to out-couple electromagnetic radiation from the first waveguide portion, within a sub-range of the wavelength range. Further, a photodetector () including a photoactive layer () is arranged at a second end () of the first waveguide portion and at an end () of the second waveguide portion, and configured to separately detect electromagnetic radiation transmitted through and exiting the first waveguide portion and the second waveguide portion.
