Abstract

Multicolor, stacked detector devices, focal plane arrays including multicolor, stacked detector devices, and methods of fabricating the same are disclosed. In one embodiment, a stacked multicolor detector device includes a first detector and a second detector. The first detector includes a first detector structure and a first ground plane adjacent the first detector structure. The second detector includes a second detector structure and a second ground plane adjacent the second detector structure. At least one of the first ground plane and the second ground plane is transmissive to radiation in a predetermined spectral band. The first detector and the second detector are in a stacked relationship.
