Josephson tunnel junction coupled to superconducting thin-film resonator

Observation and a model for resonances in one-dimensional unshunted Josephson-junction arrays with ground planes

“…Junctions can also interact with an external resonator, as is the case in the work by Larsen et al 2 The system consisted of a small junction placed inside of a strip-line resonator. The resonant cavity was external to the junction and constantvoltage features were observed in the I-V characteristic at voltages set by the resonant modes of the strip line.…”

Observation of electromagnetic coupling to a closed superconducting thin-film cavity

“…The deposition of a trapping layer around the cavity could be used to confine excess quasiparticles to the cavity walls to increase this effect. At the time of our proposal, the device specifically proposed had not been fabricated (although Larsen et aldemonstrated coupling in the case of a junction imbedded within a superconducting microstrip resonator [4]). We now report on the fabrication and testing of a junction/Fiske cavity device.…”

“…In so doing, we ignore the complications due to the junction not completely covering the upper wall of the cavity. That aside, from Josephson's equation and (1), the resonant steps are predicted to occur at voltages given by (4) where and are both nonzero. Junction/cavity devices prepared for this study were modified conventional superconducting tunnel junctions.…”
