Abstract: Embodiments of detectors made using lattice matched photoabsorbing layers are disclosed. A photodiode apparatus in accordance with one or more embodiments of the present invention comprises an indium phosphide substrate, and a photoabsorbing region comprising at least an indium gallium arsenide antimonide nitride (InGaAsSbN) layer, wherein the InGaAsSbN layer has a thickness of at least 100 nanometers and is nominally lattice-matched to the indium phosphide substrate.
