Gao, J.R. (author), Gan, Y. (author), Mirzaei, B. (author), Silva, J. R.G. (author), Cherednichenko, S. (author)Heterodyne receivers combining a NbN HEB mixer with a local oscillator (LO) are the work horse for high resolution (≥106) spectroscopic observations at supra-terahertz frequencies. We report an MgB2 HEB mixer working at 5.3 THz with<br/>20 K operation temperature based on a previously published paper [Y. Gan et al, Appl. Phys. Lett., 119, 202601...conference paper 2022

Mirzaei, B. (author), Gan, Y. (author), Silva, J. (author), Gao, J.R. (author)We will report a full demonstration of the Fourier phase grating used as 4.7 THz local oscillator (LO) multiplexer for Galactic/Extragalactic ULDB Spectroscopic Terahertz Observatory (GUSTO). The design, modeling, tolerance analysis, and experimental characterization of the angular and intensity distributions among 2 × 4 output beams and the...conference paper 2022
