Abstract:

In this chapter, novel active optoelectronic probe-tips fabricated by micromachining techniques are introduced. These devices are highly attractive for a broad range of applications requiring micron-scale resolution and terahertz (THz) range operation. Using planar waveguide designing modalities they are the first devices combining THz generation, detection, transmission and focussing elements in a single self-contained cantilever microstructure. At the beginning of the chapter a brief overview of current near-field (NF) probing approaches and their applications ...
