Abstract: A cryogenic laser transmitter includes a multi-fiber push-on (MPO) fiber adapter. The MPO fiber adapter includes an adapter housing and a laser mount. The adapter housing contains a plurality of laser diodes, each laser diode configured to generate a laser emission based on an input signal of a focal plane array. The laser mount is configured to mate with an MPO connector and direct each laser emission through to a corresponding fiber core of the MPO connector.

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.
