A Compact, Fiber-Pigtailed, Terahertz Time Domain Spectroscopy System

Authors:
D. Zimdars, J. V. Rudd, M. Warmuth
Abstract:
Terahertz time-domain spectroscopy (TDS) is a field that has been steadily growing in research labs over the last 11 years with demonstrated spectroscopic applications in semiconductors, liquids, and gases, as well as more recent applications based on 2D-imaging. However, even with the interest outside of the ultrafast community given to terahertz spectroscopy and imaging (such as the system initially developed by Nuss and co-workers and popularized as "T-Rays"), the commercialization of a THz TDS system has been hindered by its complexity. In order to build a TDS system, skills in ultrafast lasers and optics, semiconductor physics, and submillimeter waves optics are required. Even if all of the individual components, from the photoconductive antennas to the silicon lenses, were available for purchase, the resulting system would not be useful in most manufacturing or even laboratory environments due to the complexity and instability of free-space optical systems. For these technical reasons, it has been simply not feasible, until now, to take advantage of THz spectroscopy techniques outside of specialized laser science laboratories.
