Abstract:
1. A monolithic focal plane array (FPA) comprising: an array of multiple pixel unit cells disposed on a substrate, in which each pixel unit cell includes: a first array of THz antennae disposed on a top layer of the substrate, and a second array of context imaging pixels disposed on the top layer of the substrate, wherein the first and second arrays are interleaved on the top layer of the substrate, and further including: a semiconductor layer disposed below the top layer of the substrate, the semiconductor layer including first and second circuits for processing signals received from the first and second arrays, respectively, and an interconnect layer disposed between the top layer and the semiconductor layer for providing couplings between the first and second arrays and the first and second circuits, respectively, wherein the first circuit includes a summing circuit for summing each signal from a THz antenna disposed in the first array, and the first circuit provides a pixel output representing a summation of signals from the THz antennae disposed in the first array of a single pixel unit cell.
