We discuss how reactive and dissipative nonlinearities affect the intrinsic response of superconducting thin-film resonators. We explain how most, if not all, of the complex phenomena commonly seen can be described by a model in which the underlying

Transition-edge sensors (TESs) are capable of highly accurate single particle energy measurement. TESs have been used for a wide range of photon detection applications, particularly in astronomy, but very little consideration has been given to their

Transition Edge Sensors are ultra-sensitive superconducting detectors with applications in many areas of research, including astrophysics. The device consists of a superconducting thin film, often with additional normal metal features, held close to

An interferometric technique is described for measuring the spatial forms of the individual degrees of freedom through which an object or system can absorb energy from its environment. The method separates out the spatial forms of the coherent excita

We have developed a dc SQUID in which the input inductance is coupled via an on chip integrated intermediary transformer. The overall coupling factor between the 0.367 μH input coil and 30 pH dc SQUID was as large as 0.77. In order to eliminate tran
