Autor: Jia-Qiang Zhong, Wei Zhang, K. M. Zhou, Z. H. Wang, Shuyun Shi, Q.J. Yao, P. Z. Li, Yue Geng, Wei Miao, Yuan Ren, Jun Wang

Publikováno v: 2019 44th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz).

We have improved the detection efficiency of Ti-based superconducting transition edge sensor(TES) with the integration of dielectric mirror at the operation wavelength of 1550 nm. The TES fabricated on the dielectric mirror is coupled to the optical

A 1.4 THz Quasi‐Optical NbN Superconducting HEB Mixer Developed for the DATE5 Telescope

Autor: T. Vacelet, Z. Lou, Wen Zhang, J. Hu, Sheng-Cai Shi, Wei Miao, R. Lefevre, K. M. Zhou, Yan Delorme, S. L. Li

Publikováno v: IEEE Transactions on Applied Superconductivity. 25:1-5

In this paper, the performance of a twin-slot antenna coupled NbN superconducting HEB mixer based on a new device fabrication process is thoroughly investigated. The measured lowest double-sideband receiver noise temperature is about 600 K at 1.3 THz

Heterodyne Mixing and Direct Detection Performance of a Superconducting NbN Hot-Electron Bolometer

Autor: Sheng-Cai Shi, Q.J. Yao, Wei Miao, Wen Zhang, Z.H. Lin, K. M. Zhou, Shao-Liang Li

Publikováno v: IEEE Transactions on Applied Superconductivity. 21:624-627

The heterodyne mixing and direct detection performance of a superconducting NbN hot-electron bolometer (HEB) integrated with a log-spiral antenna have been thoroughly characterized. The corrected receiver noise temperature and IF gain bandwidth are a

Noise and Bandwidth of 0.5-THz Twin Vertically Stacked SIS Junctions

Autor: Sheng-Cai Shi, Jing Li, Dong Liu, K. M. Zhou, H. W. Chang, Tse-Jun Chen, Chuang-Ping Chiu, Ming-Jye Wang, Chong-Wen Chen, Wei-Chun Lu

Publikováno v: IEEE Transactions on Applied Superconductivity. 21:663-666

Twin SIS (superconductor-insulator-superconductor) junctions, with a simple structure, yet large bandwidth and low noise temperature, have been widely used in millimeter- and submillimeter-wave heterodyne mixers. With increasing frequency, however, t
