THz Radiation; a 'Big Deal' -or Small Beer?
And A Novel THz Near-Field Microscope.
サザンプトン大学 Harvey Nicholas Rutt 教授
The terahertz region, now defined as 0.3 to ten terahertz, has seen an explosion of interest in the last couple of decades. This was largely driven by the development of 'time domain' techniques. These undoubtedly hugely improved the practicality of working in the THz region. However there is a large body of earlier work, when the region was usually called the far-infrared (FIR) or sub-millimetre region, which modern 'THz' workers tend to overlook. There have been very many claims for potential commercial THz applications, but to date rather few have actually succeeded. The first part of the talk - which is rather contentious - argues that for very good, fundamental physics reasons, some of the claims made for THz applications are exaggerated.
However, it does seem that some more realistic applications of the technology may emerge. IN the second part, the operation of a novel near field THz microscope is described. It employs a new multiplexing technique to achieve a speed-up of a factor of 16, which is scalable to at least 100.
