Abstract: A photo detector having a substrate and a first structure formed on the substrate. The first structure includes an emitter layer formed on the substrate and a base layer formed on the emitter layer. Further, the first structure includes a collector layer formed on the base layer. The collector layer has a plasmonic structure. The plasmonic structure includes a first plurality of mesa structures. Each of the mesa structures of the first plurality of mesa structures includes a second plurality of mesa structures having ridges arranged in a regularly repeating pattern.

Abstract: A bolometer pixel trigger array includes a substrate, an electrically conductive contact pad formed on the substrate, and bolometer formed on the substrate. The bolometer includes at least one thermally conductive trigger arm having a fixed end coupled to a portion of the bolometer and an electrically conductive free end configured to deflect with respect to the fixed end. At least one trigger arm establishes different operating states of the bolometer pixel trigger in response to the at least one trigger arm realizing different temperatures. The different operating states are configured to change an electrical connection between the at least one trigger arm and the contact pad.
