Claim 20:
21. The thermal radiation detection system of claim 1, wherein the mercury-cadmium-telluride (HgCdTe)-based photodiode infrared detector or the InAs-based photodiode infrared detector comprises:
a plurality of layers comprising a semi-insulating Gallium arsenide (GaAs), Indium gallium arsenide (InGaAs) or Germanium (Ge) substrate in a plan view;
a first electrode electrically coupled to a first of the plurality of layers and a second electrode electrically coupled to a second of the plurality of layers; and
wherein the detected mid-infrared wavelengths are transmitted through the GaAs, InGaAs or Ge substrate to the first and second electrodes.
