Vanadium superconducting microwave resonators on silicon wafers
Y. Fujita, Y. Urade, Y. Hibino +4
Understanding the correlation between material properties and microwave losses in superconducting films is a crucial subject for developing low-loss materials for quantum circuits.…
Microwave characterization of tantalum superconducting resonators on silicon substrate with niobium buffer layer
Yoshiro Urade, Kay Yakushiji, Manabu Tsujimoto +4
Tantalum thin films sputtered on unheated silicon substrates are characterized with microwaves at around 10 GHz in a 10 mK environment. We show that the phase of tantalum with a bo…
Terahertz imaging system with on-chip superconducting Josephson plasma emitters for nondestructive testing
Manabu Tsujimoto, Kaveh Delfanazari, Takanari Kashiwagi +2
Compared with adjacent microwaves and infrared frequencies, terahertz (THz) frequency offers numerous advantages for imaging applications. The unique THz spectral signatures of che…
Mutually synchronized macroscopic Josephson oscillations demonstrated by polarization analysis of superconducting terahertz emitters
M. Tsujimoto, S. Fujita, G. Kuwano +7
We demonstrate mutual synchronization of Josephson oscillations in multiple stacks of intrinsic Josephson junctions of the cuprate superconductor BiSrCaCuO. Det…
Monolithic superconducting emitter of tunable circularly polarized terahertz radiation

We propose an approach to control the polarization of terahertz (THz) radiation from intrinsic Josephson-junction stacks in single crystalline high-temperature superconductor $Bi_2…
Cavity mode identification for coherent terahertz emission from a nearly square stack of intrinsic Josephson junctions
M. Tsujimoto, I. Kakeya, T. Kashiwagi +2
Stacks of intrinsic Josephson junctions in BiSrCaCuO emit intense and coherent terahertz waves determined by the internal electromagnetic cavity resonance. We i…
Thermal and electromagnetic properties of BiSrCaCuO intrinsic Josephson junction stacks studied via one-dimensional coupled sine-Gordon equations

We used one-dimensional coupled sine-Gordon equations combined with heat diffusion equations to numerically investigate the thermal and electromagnetic properties of a $300\,μ\math…
Broadly Tunable Sub-terahertz Emission from Internal Branches of the Current-voltage Characteristics of Superconducting Bi2Sr2CaCu2O8+d Single Crystals
Manabu Tsujimoto, Takashi Yamamoto, Kaveh Delfanazari +8
Continuous, coherent sub-terahertz radiation arises when a dc voltage is applied across a stack of the many intrinsic Josephson junctions in a Bi2Sr2CaCu2O8+d single crystal. The a…
Cavity mode waves during terahertz radiation from rectangular BiSrCaCuO mesas
