The next generation of space-based far-IR astronomical telescopes require ultra-low noise detectors for background-limited observations with cooled optics. Detectors arrays with tens of thousands of pixels spanning the 20 - 600  µm waveband and having high optical coupling efficiency will be needed to support this vision. A detector technology has yet to be identified that can meet these requirements, which would enable revolutionary science from a future space mission such as a far-IR Probe as recommended by the 2020 Decadal Survey. We address this technology gap with focused development programs in absorber-coupled transition-edge sensor (TES) bolometers. The successful candidate will contribute to a multi-disciplinary research effort that encompasses the development of astronomical focal plane instrumentation, frequency selective electromagnetic coupling structures (photonics), superconducting detectors, as well as coherent (phononic) and non-coherent (thermal) phonon transport at low temperatures. These and other related methods are used to reduce dark noise, and increase detector coupling efficiency, detection bandwidth, and array multiplexing factor.

We also have a focused effort to increase the energy-resolution of Near-IR Kinetic Inductance Detectors (KIDs) for ultra-low-background observations of exoplanet atmospheres. The KID is a promising technology that is effectively immune to the effects of particle radiation and thermal drift in a spacecraft.
