Abstract
A monolithic focal plane array (FPA) of an imaging system includes an array of multiple pixel unit cells disposed on a substrate. 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. The first and second arrays are interleaved on the top layer of the substrate. In addition, each THz antenna in the first array is shaped either in a bow-tie, circular or tuned waveguide configuration, and each context imaging pixel in the second array is shaped in a circular, or rectangular configuration.
