David Zopf:
Metal-nanoparticles have due their size and special optical properties a large potential for the development of optical devices. We have used metal-nanoparticle layer deposition inside the channels of micro structured optical fibers. The sensitivity of the so obtained plasmonic layer is about 78 nm per refractive index unit (RIU) and the fibers could serve as sensors for measuring changes in the refractive index or to sense biochemical reactions using functionalized nanoparticles.
Another application is to exploit the sensitivity of nano silver prisms using Cavity Ring Down Spectroscopy, which will be shortly explained and the status and an outlook of the recent project will be presented.
