Abstract

Highly stable and low-noise terahertz waves are crucial for applications like 6G communications, spectroscopy, and radar. Highly stable terahertz wave generation via photomixing stable optical waves require bulky and expensive equipment. We present an alternative approach transmitting stable optical comb lines over long optical fibers and a 1.3 km free-space link. At the remote site, photomixing generates terahertz waves. We assess the stability through self-heterodyne measurements, analyze link/conversion noise impacts, and conduct terahertz communication experiments with the transferred terahertz wave, aiming to support 6G hybrid networks and remote terahertz standards dissemination.
