THz imaging and microscopy, a multiplexed near-field TeraHertz microscope
… at fast acquisition rates. In the classical THz sub-wavelength imaging with a single aperture, the image is composed by mechanically scanning the sample against a single sub-wavelength aperture. Only one pixel of the final image is acquired for every integration time of a THz photodetector which …

Surface plasmons for enhanced metal-semiconductor-metal photodetectors
… The extraordinary properties of SPP allow for sub-diffraction limit waveguiding and localized field enhancement. The emerging field of surface plasmonics has applied SPP coupling to a number of new and interesting applications, such as: Surface Enhanced Raman Spectroscopy (SERS), super lenses, …
