Terahertz Direct Detection Behavior of a Superconducting NbN bolometer by Noise Thermometry

Hao Gao, Wei Miao, Kangmin Zhou +1 more

In this paper, we report the investigation of direct detection behavior of a superconducting niobium nitride (NbN) hot electron bolometer (HEB) based on noise thermometry. The HEB consists of a microbridge made from 5.5 nm thick NbN film and a twin slot antenna for radiation coupling. In the microbridge, hot electron system is generated after radiation pumping and it creates extra noise at RF frequencies. We measured the response of the noise at 0.5-1.8 GHz and the noise equivalent power (NEP) of the superconducting NbN HEB at different bias voltages. The measurement result shows that the superconducting NbN HEB has a noise equivalent power of 1.24×10-12W/Hz1/2at its optimal bias point. We also compared the noise equivalent power measured by noise thermometry at two different readout bandwidths. The measured results are found to be in good agreement with the theoretical one.

Heterodyne detection of THz radiation with a superconducting hot-electron bolometer mixer

Alexei D. Semenov, Yu. P. Gousev, Rainer S. Nebosis +6 more

We report on the use of a superconducting hot-electron bolometer mixer for heterodyne detection of terahertz radiation. Radiation with a wavelength of 119 μm was coupled to the mixer, a NbN microbridge, by a hybrid quasioptical antenna consisting of an extended hyperhemispherical lens and a planar logarithmic spiral antenna. We found, at an intermediate frequency of 1.5 GHz, a system double side band noise temperature of ≊40 000 K and conversion losses of 25 dB. We also discuss the possibilities of further improvement of the mixer performance.

Superconducting sub-millimeter diplexer suitable for pixel-size two-band bolometric detection

Philippe Camus, D. Rauly, O. Guillaudin +3 more

The design of a diplexer, coupled to a planar bowtie antenna for two-band Cosmic Microwave Background detection is proposed, using both HFSS™ and ADS™ softwares. The two photometric bands are centered on 150 GHz and 220 GHz respectively. The diplexer is composed of two three-elements distributed filtering circuits, taking into account the complex impedance of the antenna and the impedance of the two resistive loading bolometers. The distributed elements are transmission lines Coplanar Strip Lines (CPS) and Broadside Coupled Lines (BCL). Their balanced geometry matches to the differential signal delivered by the bow-tie antenna, avoiding the addition of a balun circuit. The envisaged technology for strips and antenna is superconducting niobium at a few 100mK on Si substrate. The overall size of the antenna/diplexer structure is around 2 mm2, allowing to consider it as a pixel suitable for integration in a bolometer array.
