Detection of microwave radiation using thin film superconducting loops containing weak links

Abstract

Thin film superconducting SQUIDs biased at 30 MHz have been used for the detection of electromagnetic radiation in the frequency range from about 1 kHz up to at least 10 GHz. With the improved performance obtained for microwave-excited devices, detection of mm and sub-mm radiation should be possible. Calculated sensitivity for a microwave excited SQUID to radiation at 100 GHz is about 10-17 W/√Hz.

High T c refractory thin-film microwave SQUID’s

Frederic J. Rachford, Edward J. Cukauskas

Thin-film SQUID’s fabricated from the high Tc refractory material NbN have been studied at 9.4 GHz. Devices with granular weak links display a Josephson critical current dependence over a wide range of temperatures below Tc. We have observed open loop signal-to-noise ratios as high as 20 000 corresponding to a minimum detectable energy of 1×10−30 J in a 1 Hz bandwidth over a temperature range of several °K. In two samples, the response time was found to be limited by the intrinsic gap response time, τg∼h//2Δ (T). These devices are rugged, stable, cycle well, and have good SQUID properties at both 9.4 GHz and 20 MHz.

High-Tc superconducting detector for highly-sensitive microwave magnetometry

F. Couëdo, Eliana Recoba Pawlowski, Julien Kermorvant +8 more

We have fabricated arrays of High-Tc Superconducting Quantum Interference Devices (SQUIDs) with randomly distributed loop sizes as sensitive detectors for Radio Frequency (RF) waves. These subwavelength size devices known as Superconducting Quantum Interference Filters (SQIFs) detect the magnetic component of the electromagnetic field. We used a scalable ion irradiation technique to pattern the circuits and engineer the Josephson junctions needed to make SQUIDs. Here, we report on a 300 SQUID series array with the loop area ranging from 6 to 60 μm2, folded in a meander line covering a 3.5 mm × 120 μm substrate area, made out of a 150 nm thick YBa2Cu3O7 film. Operating at a temperature of T = 66 K in an unshielded magnetic environment under low DC bias current (I = 60 μA) and a DC magnetic field (B = 3 μT), this SQIF can detect a magnetic field of a few picoteslas at a frequency of 1.125 GHz, which corresponds to a sensitivity of a few hundreds of fT/Hz and shows a linear response over 7 decades in RF power. This work is a promising approach for the realization of low dissipative subwavelength gigahertz magnetometers.

Microwave properties of thin film NbN SQUIDs with granular weak lines

R. Steiner, Allen Paige Flora, Bascom S. Deaver +1 more

A series of NbN thin film SQUIDs with transition temperatures ranging from 5 K to ∼14 K are being characterized by microwave measurements at 9.6 GHz. The data are being used to determine the critical current, resistance, and energy sensitivity of each device, to identify features that may be related particularly to the granular nature of the weak links, and to study systematically the variations of the SQUID response with temperature. The devices are nominally 1 μm long, 10 nm thick and from 1 μm to ∼50 μm wide and are fabricated on 1 mm-diameter quartz rods. All have previously been well characterized as SQUIDs at 23 MHz. Detailed results are presented for the first five devices studied.

Microwave detectors based on granular high-T/sub c/ thin films

Janusz Konopka, Roman Sobolewski, Grzegorz Jung +4 more

The detecting and mixing properties of microstrip superconducting Y-Ba-Cu-O and Bi-Ca-Sr-Cu-O thin-film structures deposited on various substrates have been investigated. The device performance was tested in the 22-, 55-, and 110-GHz frequency bands at temperatures ranging from 100 K to about 50 K. The sensitivity obtained at 110 GHz was comparable to that of crystalline detectors. Mixing experiments were performed in the 25-GHz frequency band and indicated that the detector response time is less than 40 ps. The intermediate frequency was varied from 50 MHz to 5 GHz without any decrease in the mixer output up to 3 GHz. Auxiliary emission measurements performed at 12 GHz and down to 4.2 K revealed that the detector low-temperature performance limit is associated with microwave radiation from clusters of intergrain weak links arranged in multiloop quantum interferometers.>

Development of Microwave SQUID Multiplexer for Readout of Transition-Edge Sensor Array

Zhi-Fa Feng, Xianfeng Zhou, Wen Zhang +12 more

Superconducting transition-edge sensors (TESs) with high sensitivity can detect electromagnetic wave radiations from millimeter/submillimeter, optical to x/γ rays, and have been successfully used in many fields. To improve detection efficiency and sensitivity, large-scale TES arrays are required in combination with multiplexing readout electronics. Compared to other multiplexing schemes, microwave SQUID multiplexing (μMUX), consisting of high-quality microwave superconducting resonators and RF SQUIDs, is most suitable since it provides a wider bandwidth (GHz) and consequently higher multiplexing factor. We designed two types of circuits with different mutual inductances (MT) between the resonator and the RF SQUID: 2.3 pH for the weak-coupling channel and 6.5 pH for the strong- coupling channel. The resonator and RF SQUID washers made of 150 nm Nb are first fabricated by magnetron-sputtering and reactive ion etching (RIE), followed by deposition of Nb/Al-AlOx/Nb trilayer and definition of the Josephson junctions of the RF SQUIDs. This work presents a μMUX demonstration chip with five channels with Q1values of 787 and 3626, and the measured frequency shifts (Δfpp) of ∼500 kHz and 4 MHz for the weak- and strong-coupling channels, respectively. The open-loop equivalent noise current, obtained from the measured phase noise and resonator responsivity, is ∼80 pA/ √Hz with the strong-coupling channel.

Small-signal microwave impedance measurements of a superconducting thin-film microbridge

P W Forder, John Ryder Waldram

Measurements at 3 GHz of the microwave properties of a superconducting thin-film microbridge coupled to a narrowly tuned strip-line resonator (coupled Q approximately 10 3 ) indicate that such a device displays the same variations in small-signal impedance as predicted by the resistively shunted junction model of a Josephson weak-link. Whenever this impedance becomes negative the microbridge is found to generate microwave radiation whose frequency is determined not by the junction bias voltage but by the natural resonance of the strip-line.
