Characterising the optical response of ultra-low-noise far-infrared 60-110 m transition edge sensors
Emily A. Williams, Stafford Withington, David J. Goldie +3
Far-infrared Transition Edge Sensors (TESs) are being developed for the SAFARI grating spectrometer on the cooled-aperture space telescope SPICA. In support of this work, we have d…
Spin resonance linewidths of bismuth donors in silicon coupled to planar microresonators
James O'Sullivan, Oscar W. Kennedy, Christoph W. Zollitsch +5
Ensembles of bismuth donor spins in silicon are promising storage elements for microwave quantum memories due to their long coherence times which exceed seconds. Operating an effic…
Loss and Saturation in Superconducting Travelling-Wave Parametric Amplifiers
Songyuan Zhao, Stafford Withington, David J. Goldie +1
We have developed a coupled-mode analysis framework for superconducting travelling-wave parametric amplifiers using the full Telegrapher's equations to incorporate loss-related beh…
Identification of the absorption processes in periodic plasmonic structures using Energy Absorption Interferometry
Denis Tihon, Stafford Withington, Christopher N. Thomas +1
Power dissipation in electromagnetic absorbers is a quadratic function of the incident fields. To characterize an absorber, one needs to deal with the coupling that may occur betwe…
Superconducting transition edge sensors with phononic thermal isolation
Emily A. Williams, Stafford Withington, Christopher N. Thomas +2
The sensitivity of a low-noise superconducting transition edge sensor (TES) is determined by the thermal conductance of the support structure that connects the active elements of t…
Thermal elastic-wave attenuation in low-dimensional SiN bars at low temperatures
Stafford Withington, Emily Williams, David J. Goldie +2
At low temperatures, < 200 mK, the thermal flux through low-dimensional amorphous dielectric bars, < 2 m wide and 200 nm thick, is transported by a small number of low-order ela…
