4x2 Hot electron bolometer mixer arrays for detection at 1.46, 1.9 and 4.7 THz for a balloon borne terahertz observatory
José R. G. Silva, Wouter M. Laauwen, Behnam Mirzaei +10
We have demonstrated three 4x2 hot electron bolometer (HEB) mixer arrays for operation at local oscillator (LO) frequencies of 1.46, 1.9 and 4.7 THz, respectively. They consist of…
Post-fabrication frequency trimming of coplanar-waveguide resonators in circuit QED quantum processors
S. Vallés-Sanclemente, S. L. M. van der Meer, M. Finkel +9
We present the use of grounding airbridge arrays to trim the frequency of microwave coplanar-waveguide (CPW) resonators post fabrication. This method is compatible with the fabrica…
Free-space sub-terahertz field-polarization controlled by waveguide-mode-selection
Marc Westig, Holger Thierschmann, Allard Katan +2
We study experimentally the free-space electro-magnetic field emitted from a multimode rectangular waveguide equipped with a diagonal-horn antenna. Using the frequency range of 215…
Analysis of a single-mode waveguide at sub-terahertz frequencies as a communication channel
Marc Westig, Holger Thierschmann, Allard Katan +2
We study experimentally the transmission of an electro-magnetic waveguide in the frequency range from 160 to 300 GHz. Photo-mixing is used to excite and detect the fundamental TE10…
Local electrodynamics of a disordered conductor model system measured with a microwave impedance microscope
Holger Thierschmann, Hale Cetinay, Matvey Finkel +4
We study the electrodynamic impedance of percolating conductors with a pre-defined network topology using a scanning microwave impedance microscope (sMIM) at GHz frequencies. For a…
Shielded cantilever with on-chip interferometer circuit for THz scanning probe impedance microscopy
Matvey Finkel, Holger Thierschmann, Allard J. Katan +3
We have realized a microstrip based THz near field cantilever which enables quantitative measurements of the impedance of the probe tip at THz frequencies (0.3 THz). A key feature…
Spatial conductivity mapping of unprotected and capped black phosphorus using microwave microscopy
Pieter J. de Visser, Rebekah Chua, Joshua O. Island +5
Thin layers of black phosphorus present an ideal combination of a 2D material with a tunable direct bandgap and high carrier mobility. However the material suffers from degradation…
