Bridging the terahertz gap for chaotic sources with superconducting junctions
journal contribution
posted on 2019-02-15, 15:04 authored by D Gulevich, V.P. Koshelets, Feodor KusmartsevWe observe a broadband chaotic signal of terahertz frequency emitted from a superconducting junction. The
generated radiation has a wide spectrum reaching 0.7 THz and power sufficient to drive on-chip circuit elements.
Our experimental finding is fully confirmed by numerical modeling based on microscopic theory and reveals the
unrealized potential of superconducting systems in chaos-based terahertz communication, fast generation of true
random numbers, and noninvasive terahertz spectroscopy.
