Optical/UV single-photon imaging spectrometers using superconducting tunnel junctions
We present preliminary test results of optical/UV single-photon imaging spectrometers using superconducting tunnel junctions. Our devices utilize a lateral trapping geometry. Photons are absorbed in a Ta thin "lm, creating excess quasiparticles. Quasiparticles di!use and are trapped by Al/AlO x /Al tunnel junctions located on the sides of the absorber. The Ta/Al interface does not overlap the j...
متن کاملSuperconducting Nb-Ta-AI-AIOx-AI Tunnel Junctions for X-Ray Detection
We report progress on the microlithographic fabrication of Nb-Ta-AI-AlOx-AI structures designed for x-ray detection. These structures use bandgap engineering both for quasiparticle trapping to increase the collection efficiency and to prevent quasiparticle diffusion out through the leads. Non-standard tunnel junction geometries are used to reduce the magnetic field needed to suppress the Joseph...
متن کاملTantalum superconducting tunnel junctions for infrared photon counting
Superconducting Tunnel Junctions (STJ) are currently being developed as photon detectors for a wide range of applications. Interest comes from their ability to cumulate photon counting with chromaticity (i.e. energy resolution) from the Near InfraRed (NIR) to the X rays wavelengths and excellent quantum efficiency up to 80%. Resolving power can reach more than 10 in the visible. Our main goal i...
متن کاملWaveguide integrated superconducting single-photon detectors with high internal quantum efficiency at telecom wavelengths
Superconducting nanowire single-photon detectors (SNSPDs) provide high efficiency for detecting individual photons while keeping dark counts and timing jitter minimal. Besides superior detection performance over a broad optical bandwidth, compatibility with an integrated optical platform is a crucial requirement for applications in emerging quantum photonic technologies. Here we present SNSPDs ...
