Abstract: A source of terahertz (THz) frequency range based on a long Josephson junction is proposed and studied experimentally. The emission is transmitted to open space using a slot antenna located on a single chip with the oscillator and matched to collecting lens. We fabricated and studied several designs of the emitter developed for frequency ranges of 250 – 410 GHz, 330 – 530 GHz and 390 – 700 GHz with continuous frequency tuning. The spectral characteristics of output emission are studied using a THz spectrometer based on the superconducting receiver with spectral resolution of about 0.1 MHz. The antenna characteristics in full range of operation are studied using a cooled silicon bolometer with high sensitivity. Experimental results match to numerical simulations.
Keywords: terahertz oscillators, Josephson effect, slot antennas, harmonic mixers.
