Widely-Tunable Laser-Sideband THz Source For Spectroscopy & LO Applications

Abstract:
There has been a recent resurgence of interest in spectroscopy in the THz. The development of "short-pulse" THz sources, and the measurements made with these sources, have pointed to a number of possible applications for THz imaging and spectroscopy in biology, medicine, and semiconductor device packaging characterization. While the "short-pulse" sources offer wide-range, low resolution, THz coverage, they have a number of drawbacks for measurement applications. The work described here represents an alternative that avoids many of these drawbacks. The work outlined in this paper marries the recent developments in high-reliability, compact THz lasers, with recent advances in Schottky-based sideband generators, to yield a reliable, potentially milliwatt-level, tunable THz source. While this work has been focussed on spectroscopy applications, the results can also be applied to provide tunable THz local oscillators.
