In a multimode FPA, all of the FPA's conducting layers including all of the absorbing layers are patterned to form electrically isolated commons for at least two, and in some instances all of the photodetector sub-arrays, to support independent mode biasing of the photodetectors. Because the commons are electrically isolated, the bias voltages are not constrained by the CMOS design rules. The commons can accommodate large bias amplitude differences and different temporal bias profiles to address a wide range of multimode sensing applications.
